FCC Class B
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interfer-
ence when the equipment is operated in a residential environment. This
equipment generates, uses and can radiate radio frequency energy. If not
installed and used in accordance with this user's manual, it may cause
harmful interference to radio communications. Note that even when this
equipment is installed and used in accordance with this user's manual,
there is still no guarantee that interference will not occur. If this equip-
ment is believed to be causing harmful interference to radio or television
reception, this can be determined by turning the equipment on and off. If
interference is occurring, the user is encouraged to try to correct the inter-
ference by one or more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and the receiver
• Connect the equipment to a power outlet on a circuit different from that
to which the receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
Warning! Any changes or modifications made to the
equipment which are not expressly approved by
the relevant standards authority could void your
authority to operate the equipment.

Chapter 1 General Information
1.1 Introduction
The PCM-3524 converts RGB video and sync from a standard VGA
source into broadcast quality NTSC or PAL video. Composite and S-
Video outputs are compliant with SMPTE-170M and CCIR-656 specifi-
cations. A fully integrated 3-line adaptive flicker filter provides three
selectable operating modes. The PCM-3524 conforms to NTSC and PAL
standards using a single low-cost application circuit. Included is all of the
active circuitry required to generate a television signal with outstanding
image quality in a standalone application. Incoming VGA source signals
must be within a ±2% tolerance of 2X the frame and 2X the line rate of
the outgoing TV standard.
1.2 Features
• Flicker free VGA-to-TV signal converter
• 3-Channel 8 bit input conversion
• Multiple input formats: 640x480 60/75/85Hz, 800x600 60/75 Hz,
1024x768 60 Hz
• Multiple output formats - NTSC, NTSC-EIA, PAL-B/G/H/I
• Composite and S-video output formats
• Horizontal and vertical positioning control
• Configuration set by switches
• Internal color bars
• 3-Channel 9-bit output D/A converters
• Blanks to blue or black screen

Chapter 2 Installation
2.1 Jumpers
You may configure your card to match the needs of your application by
setting jumpers. A jumper is a metal bridge used to close an electric cir-
cuit. It consists of two metal pins and a small metal clip (often protected
by a plastic cover) that slides over the pins to connect them. To “close” a
jumper, you connect the pins with the clip. To “open” a jumper, you
remove the clip. Sometimes a jumper will have three pins, labeled 1, 2
and 3. In this case you would connect either pins 1 and 2, or 2 and 3.
The jumper settings are schematically depicted in this manual as follows:.
A pair of needle-nose pliers may be helpful when working with jumpers.
If you have any doubts about the best hardware configuration for your
application, contact your local distributor or sales representative before
you make any changes.
Generally, you simply need a standard cable to make most connections.

Making the proper jumper settings to configure the PCM-3524 to match
the needs of your application.
2.2.1 PAL/NTSC Video Output Select (JP1, JP2, JP4):
Timing, sub-carrier frequency, and phase parameters are preprogrammed
into the module and correspond to worldwide NTSC and PAL standards.
Use TD0 and TD1 to select one of four sets of parameters to set up the
encoder. The frame rate of the graphics source must be twice the frame
rate of the selected video standard. Please see Table 2.2

2.2.2 PWRDN Power-Down Control (JP5)
When closed, the PCM-3524 is fully operational and enabled. When
opened, the PCM-3524 is configured for minimum power consumption.
D/A converters and clocks are disabled. Previously established set-up
conditions are retained and remain in effect when PWRDN is shorted
again.
2.2.3 RGB_OUT Enable (JP6)
When opened to ON, the PCM-3524 is configured for RGB output, the
COMPOSITE, LUMA, and CHROMA will output R, G, and B respec-
tively. When shorted to OFF, RGB output is disabled.
2.2.4 YUV_OUT Enable (JP8)
When open to ON, the PCM-3524 is configured for YUV output, the
COMPOSITE, LUMA, and CHROMA will output Y, U, and V respec-
tively. When short to OFF, YUV output is disabled.
2.2.5 POWER Selection (JP14)
When short 1-2, the power source from +5V. When short 2-3, the power
source from regulator.

2.4 Switches and VR
All switches are pin-headers. Some sort of switches must be connected,
such as a button switches.
2.4.1 Reset (SW1)
Momentary contact reboots the system.
2.4.2 Position controls (SW2~5)
The position controls change the processor timing relative to incoming
video so that the viewed image may be shifted right or down, to reveal
portions of the image that may be found near the edges or in the overscan
areas. Vertical position is adjusted 2 lines per frame, for a total of 128
lines. Video image will revert to the most upper left position. In the 4-tog-
gle position mode, reversion is not supported and all 4 positioning con-
trols have to be used in order to scroll back the image. During Zoom
operation, the 4 positioning controls remain available, and are used for
panning the image across the active video area.

2.4.3 ZOOM TOGGLE (SW6)
When SW6 is pulsed, the video image size doubles in both the horizontal
and vertical directions (this makes the image 4x larger). The video image
display can be set back to normal size by another pulse.
2.4.4 BLANK (SW7)
When closed, a blank blue screen is displayed.
2.4.5 FREEZE (SW8)
When closed, writing to the external field store devices stops on the next
falling edge of VSYNC. When open, writing to the external field store
devices resumes on the next falling edge of VSYNC.
2.4.6 FILTER MODE SELECTION (SW9)
Vertical Filter Mode select. The 3-line flicker reduction filter may be con-
figured for 3-line filtering, 2-line filtering, and no vertical filtering
modes. Pulsing the FILTER control will cycle through the different filter-
ing modes.
