1. DESCRIPTION
1.1. The PDS3000C01
The PDS3000C01 is an analog composite video to SDI digital video converter. The module
incorporates a frame memory in order to synchronize the digital video output with an
external digital reference signal.
The analog to digital video conversion employs a 10 bit digitizer with a sampling
frequency of 27MHz obtained from a quartz oscillator in order to obtain a high quality
digital signal. Extraction of the three video components is performed with an adaptive
comb filter in the digital domain.
The PDS3000C01 provides an adjustable, digital equalizer for compensation of the
frequency response of the cabling used for the analog input. Luminance, chrominance
and black levels can also be adjusted by the user.
The module can operate as a video delayer or as a frame synchronizer. In Frame
Synchronization mode the SDI output is synchronized to the digital reference input. In
Video Delayer mode the SDI video signal is synchronized to the analog video signal and
the digital reference input is not used.
In either operating mode the user can adjust the delay of the output signal in order to
obtain delays of up to one frame, with a resolution of 37 ns. Use of the digital reference
signal provides an elevated level of precision and stability for the output signal.
The user can configure the composite video decoder to operate in three different ways:
using an adaptive comb filter, performing a simple separation with a low pass filter for
the luminance and band pass filter for the chrominance and via a simple separation with
a notch filter for the luminance and band pass filter for the chrominance.
Control over the operating mode, configuration of the delays and processing of the
output signal can all be performed from the front panel o from a computer when the
mounting frame in which the PDS3000C01 is installed has a communications control
module as well.
The front panel of the module contains LEDs that indicate errors in the digital reference,
in the input composite video signal and in the synchronization status.
The PDS3000C01 module performs a complete processing of the checksums of the SDI
reference signal and inserts EDH packets into the digital stream for error detection as per
SMPTE RP 165.
The rear board of the module includes a bypass relay that can connect the SDI video
reference input to one of the outputs. This guarantees signal continuity for one of the
5

Albalá Ingenieros | Manual PDS3000C01
outputs in case of a power supply failure. It is also possible that a frozen image followed
by video black or an output of the reference signal (a courtesy signal) result from loss of
the composite video signal.
When the unit operates in Synchronizer Mode the information regarding the delay
between the input and the output is provided over a coaxial connector. The duty cycle of
the signal at the frame frequency is proportional to the delay between the input and the
output.
It is possible to monitor the PDS3000C01 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.
The PDS3000C01 is a TL3000 terminal line module and can be housed in a three rack
unit (3 RU) UR3000 mounting frame or a 1 RU UR3100 mounting frame.

3. INSTALLATION
THE PDS3000C01 MODULE CONTAINS ELECTRONIC DEVICES SENSITIVE TO
ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified
with a high degree of shielding for storage and transportation.
The PDS3000C01 module is composed of two parts: one PDS3000P01 main board and
one PDS3000P02 rear board. Both parts must be installed in a UR3000 or UR3100
mounting frame following the instructions in the corresponding section of this chapter.
3.1. Initial inspection
Verify that the package has been properly handled during transport. After opening the
packaging, check that one PDS3000P01 main board and one PDS3000P02 rear board are
inside.
You must notify your Albalá Ingenieros distributor or dealer of any damage or defects
observed.
Follow the instructions in this manual to install this module in the mounting frame.
3.2. Safety instructions
•This equipment must be connected to a mains outlet with a protective
earth connection. Never use extension cords that do not have protective
earthing connection. The lack of an effective electrical connection between
the ground pin in the mains input connector of the equipment and the
protective earth of the electrical power distribution can cause serious harm.
•All modules of the Albalá Ingenieros TL3000 terminal line can be
hot-plugged or unplugged without suffering any damage or affecting the
processes that are currently taking place in other modules in the same
mounting frame. When a module is installed in an empty bay of a mounting
frame, it is necessary to mount the rear board that is part of that module.
Prior to installing this board, the mounting frame must be disconnected
from the power supply network. This is required because in addition to the
risk of electrocution for the person handling the device it is possible that a
high instantaneous current coming from the power supply could damage
the connectors and components of the mounting frame and/or the rear
board.
11

Albalá Ingenieros | Manual PDS3000C01
•The PDS3000C01 module and the mounting frame should always be
installed, maintained, operated and removed by personnel with sufficient
technical qualifications. The equipment should never be placed in damp
areas, near splashing liquid, or in explosive or corrosive atmospheres.
Neither modules nor mounting frames can be used in applications that
could endanger human life.
3.3. Environmental considerations
This symbol indicates that this equipment must be deposited at a collection
point for proper waste treatment once it has reached the end of its useful
life.
3.4. Power considerations
The UR3000 and UR3100 mounting frames can house as many PDS3000C01 modules as
will fit in them.
3.5. Module configuration
The PDS3000C01 module contains several microswitches that must be configured
before it is inserted into a mounting frame. The configuration set by the microswitches
can be modified using the control software, however when the unit is first powered on
the microswitch settings take precedence. Switch S1 sets the operating mode of the
module as shown in the following table.
S1 OFF ON
1TV STD 625 525
2TTX PASS RMV
3FLT1 BLK FRZ
4FLT2 REF FLT1
5DECOD BAND NTCH
-TV STD: Configures the module for use with 625 line PAL signals (OFF-625) or 525 line
NTSC (ON-525).
-TTX: Configures the module to either eliminate the teletext signals (ON-RMV or to
embed them into the luminance information of the SDI signal (OFF-PASS).
-FLT1 and FLT2: These configure the module's response to a loss of the CCVS signal.
There are three possible operating modes: switching to the reference signal and
freezing the re-synchronization process: (FLT1:X,FLT2:OFF-REF), switching to video
black (FLT1:OFF-BLK,FLT2:ON-FLT1) and freezing the field for 30 seconds and then
passing to video black after a specified period of time (FLT1:ON-FRZ,FLT2:ON-FLT1).
12

Albalá Ingenieros | Manual PDS3000C01
-DECOD: Configures the operating mode of the composite video decoder when the
adaptive comb filter is not used. The luminance and chrominance can be separated
with a low pass filter and band pass filter, respectively (OFF-BAND) or the luminance
can be separated with a notch filter in the color subcarrier frequency and the
chrominance separated with a band pass filter (ON-NTCH).
The modules come from the factory with the following settings: 625 line PAL, teletext
coded into the luminance information of the SDI signal, switch to video black if the CCVS
signal is lost and separation of the luminance and chrominance with low pass and band
pass filters, respectively.
3.6. Installing the module in the mounting frame
The steps needed to install the PDS3000C01 module with the rear board in the
mounting frame are:
1 - Disconnect all power cords from the power supplies of the mounting frame.
2 - Remove the blank panels covering the front and rear of the empty bays chosen for
installing the PDS3000C01 in the mounting frame.
3 - Install the PDS3000P02 rear board ensuring that its 12-pin connectors are properly
aligned with the mounting frame´s mating connectors. Check that the orientation of
the board is correct by looking at the placement of the text printed on it according to
the illustration below.
4 - Attach the rear board to the mounting frame with two M3 metric screws and tighten.

3.7. Interconnection
The following figure shows the PDS3000C01 module rear board connector layout.
Rear view of the PDS3000C01
The PDS3000C01 provides one digital video reference input (SDI REF) and two digital
video outputs (SDI OUT1 y SDI OUT2). The connector labeled SDI OUT1 is protected by the
bypass relay such that continuity of the reference input signal is maintained in case of a
power supply failure or extraction of the module. The module also has two connectors
with loop-through for analog video (CCVS IN), and if only one is used then the other
should be terminated with a resistance of 75Ω. In addition the module has an output
(VID DELAY) that delivers pulses with a duty cycle proportional to the delay between the
input and output. Finally, the module has two GPIOs, (IO1 and IO2).
The rear interconnection board is not designed to withstand mechanical stress. The
wiring must be fastened properly to the frame where the mounting frame is housed to
prevent the rear board from supporting the weight of the cables.

Albalá Ingenieros | Manual PDS3000C01
3.7.1. Electrical SDI video connections
All electrical SDI video connections are BNC type. The following suggestions should be
kept in mind when wiring the electrical signals.
BNC connectors used on cables must be suitable for the high frequencies of digital
video signals: it is strongly recommended to use high quality connectors from well
known manufacturers.
All coaxial cable used must be Belden 8281 or similar. This type provides the greatest
lengths because it is used to calculate the equalizers in the PDS3000C01. Cables
carrying signal between the module and the devices should use single piece
construction, avoiding spliced sections with double BNC female or barrel connectors.
If it is necessary to split the cable into two sections the same type of wire should be
used in both sections.
The use of analog video coaxial cables RG-59 type or similar is not recommended for
digital video except for very short distances.
3.7.2. Analog video connections
The analog video inputs use two BNC connectors configured in loop-through.
For analog video connections a coaxial cable with 75Ω of characteristic impedance
must be used.
If the loop-through functionality of this output is not used then it should be
terminated with 75Ω.
3.7.3. GPIO connections
The GPIO inputs use 3.81mm pitch terminal block connections and have the
following equivalent circuit:

Consult the maximum values listed in the specifications section of this manual before
making any connections to the GPIOs. Never connect hazardous voltages to the GPIO
inputs.
