Information About the DLC170
Chassis Compatibility: DL4000, DL4300, DL4360x
This manual introduces the DLC170 function modules, which are available in the following models:
• DLC170AD—Converts NTSC or PAL analog video and audio to 270 Mb/s Component SD-SDI (SMPTE
259M) with embedded audio. For more information about this module, see the“Understanding and
Using the DLC170AD” section on page 2.
• DLC170DA—Converts optically received 270 Mb/s Component SD-SDI to composite analog video
(NTSC or PAL) and de-embeds audio to analog or AES digital.This module can also be used to repeat
the received optical signal. For more information about this module, see the“Understanding and
Using the DLC170DA” section on page 21.
You can use the modules separately or as a set. When used as a set, these modules ensure fullTV-1 RS250-C
Short Haul analog performance over a true SMPTE 259M SD-SDI optical transport link.
Provisioning and monitoring of the DLC170 modules is accomplished using DIP switches, LEDs, front panel
monitor jack, or Artel’s DL Manager, which is an element management system (for more information, see the
DL Manager Setup and Operations Manual). The modules also have a set of major and minor alarms for
indicating problems related to the power supplies, optics, temperature, and input signals.
Both DLC170 modules can interoperate with other DigiLink platform video function modules and other SDI
optical transmitters and receivers.

DLC170 Laser Warnings
The SFP module used in the DLC170 has a transmitter that contains a Class 1 laser.You must adhere to the
standard safety practices for handling a Class 1 laser product, including the following warning.
Warning
Never stare directly into a ber optic connector.
Although the light used in most ber optic transmissions is not visible to the naked eye, potentially
harmful levels of radiation may be present at the optical output ports and unconnected transmit ber
ends.
Failure to observe this warning could result in personal injury.
Understanding and Using the DLC170AD
The DLC170AD uses advanced high performance 12-bit video processing with adaptive 3D comb lters to
convert NTSC-M or PAL-B/G analog composite video into ITU-R BT.601/656 compliant, 525 or 625 line, 4:2:2
component digital video. The DLC170AD converts four channels of analog audio sampled at 48kHz and then
embeds the signals as either 20-bit or 24-bit samples into the digital video per SMPTE 272M for a total of four
analog channels.You can insert the audio into any one of the four groups.
Using the backplane to provide jumper-free connections, you can add additional audio channel groups by
cascading the DLC170AD digital output into one or more DLC150E audio embedders (see the DLC150E
Function Module Installation and Operations Manual). This allows up to 16 audio channels (all four SMPTE 272M
groups) to be embedded into a single DL4000 4-slot chassis. An SFP installed in the nal DLC150E module
provides the optical output of the combined signals.
The DLC170AD front panel monitor jack can output either analog or digital video. When set to analog, you can
check the incoming analog video for signal level and quality using conventional analog video equipment.
Setting the monitor jack to digital enables you to use digital video test equipment to check the converted
video in 270 Mb/s SDI format with embedded audio.
The DLC170AD features include the following:
• Single card composite video and analog audio to SDI conversion with optical transmitter (electrical-
to-optical)
• Converts composite video (NTSC/PAL) to SDI (SMPTE 259M):
– Analog composite 75Ohm video input BNC

DLC170AD Functional Description
This sections provides a functional description of the DLC170AD, including the functional block diagram
shown in Figure 1.

• Signal Paths (page 4)
• Video Input (page 5)
• Audio Input (page 5)
• Electrical Output (page 5)
• Optical Output (page 5)
Signal Paths
The DLC170AD receives an electrical composite analog video signal (either NTSC or PAL), which it converts to
component digital video and then formats it into SDI (SMPTE 259M). The DLC170AD also receives four
balanced analog audio signals and converts them into two AES-3 digital audio signals that it embeds into the
SDI digital video. The SFP module on the DLC170AD converts the resulting digital video signal to an optical
video signal.
In addition to providing the optical SDI signal, the DLC170AD output is available to other cards in the host
chassis. For example, you could use the output of the DLC170AD as one of the inputs to a DLC274M
multiplexer (see the DLC274 Function Module Installation and Operations Manual).

DLC170 Function Modules Installation and Operations Manual 5
Understanding and Using the DLC170AD
Video Input
The DLC170AD accepts video signals through the 75Ohm BNC connector located on the rear panel of the
module.This connector is the only source of analog video for the DLC170AD. When no video is available on
the selected input, the DLC170AD enables the standby video generator, which you can congure for one of
the following signal types:
• Grey screen at 525 lines (NTSC) or 625 lines (PAL) into which audio can be embedded
• Non-video keep-alive
Use the non-video keepalive signal to keep the optical link alive when an application requires that the standby
video generator not produce a detectable video signal (you cannot embed audio into the non-video
keepalive signal). Other function modules in the host chassis, such as the DLC103A, detect the keepalive
signal and signal that it is intentionally being sent across the optical link. Whenever the DLC170AD transmits
the grey screen or the non-video keepalive signal, the TX LED on the front panel illuminates yellow.
Audio Input
The DLC170AD accepts audio signals through a quad three-pin terminal block that consists of 12 pins.This
terminal accepts up to four balanced analog audio signal inputs, each with a positive (+), negative (-), and
ground (G) connector. The four balanced analog audio inputs are organized as two stereo pairs; left & right
channels.You terminate each input with either a nominal 600Ohms or a high impedance input (see the
“Conguring Audio Termination with DIP Switch SW4” section on page 11).
The DLC170AD converts the analog signals to digital signals with 24-bit audio A/Ds sampling at a rate of
48kHz. The digitized signals are then encoded into an AES-3 stream that the DLC170AD embeds into the
digital video in either 20-bit or 24-bit format.
An eight-position rotary switch allows you to set the A/D 0dBFS level from +10dBm to +24dBm into
600Ohms in 2dB steps (see the“Conguring Peak Analog Audio Level with Rotary Switch SW6” section on
page 12). You can also use Artel’s element management system, DL Manager, to set the 0dBFS level.
Electrical Output
The DLC170AD outputs a copy of the SDI electrical signal to the backplane for use by other modules in the
host chassis.
The front-panel monitor jack is a mini 75Ohm SMB connector that allows you to monitor either the analog
composite video input or the DLC170AD SDI digital video output. When adjusting cable equalization, the
monitor jack provides a view of the analog video signal.
Optical Output
A single SFP socket on the DLC170AD provides the optical interface. Optical performance is dependant the
quality of your optical ber and ber interconnects, and on the selected SFP, which must be specically
qualied by Artel to pass video signals.The SFP modules use LC/PC connectors. Consult Artel for available SFP
options.

Conguring the DLC170AD
This section describes how to congure the operation of the DLC170AD.You must congure the module while
it is out of the host chassis because the conguration DIP switches are mounted to the top of the module PCB.
DIP switches SW1, SW2, and SW4, slide switch SW5, and rotary switch SW6 are located on top of the DLC170AD
PCB (see Figure 15) and determine the operating conguration of the DLC170AD as follows.
