Introduction
The DVICOMP-IS is a scan converter module that accepts progressive scan DVI
signals at resolutions up to 1280 x 1024 from any standard graphics card for
conversion to NTSC or PAL composite. The module is a standard PCI-104 form
factor module.
The DVICOMP-IS is an intelligent stand-alone device with its own on-board CPU
and does not require device driver software. It can however be mounted on the
PCI-104 stack for mechanical convenience without consuming host CPU
resources.
The DVICOMP-IS also features a mini PCI socket that enables an AMP video
codec module to be hosted on a PC/104- Plus or PCI-104 stack.
AMP can provide custom configurations (subject to a minimum order quantity) for the
DVICOMP. Please contact our Sales team (see A: Contacting Advanced Micro
Peripherals, page 17) to discuss your requirements.

Functional summary
Video Scaling
The DVICOMP-IS provides automatic vertical and horizontal up-scaling and
down-scaling of the input video, allowing resolutions of up to 1280x1024 to be
displayed on a 625 line (PAL) or 525 line (NTSC) video monitor.
Video Encoder
The video encoder features composite output with sync.
Host interface
The core functionality of the DVICOMP-IS is completely autonomous to the
host PCI bus. The DVICOMP-IS is factory configured for NTSC or PAL output
operation and will auto-detect the input resolution prior to performing the
rescaling.
The PCI host bus is connected directly only to the [optional] mini PCI socket
and enables a range of mini PCI modules to be fitted to the board. The
DVICOMP-IS is specifically designed to accommodate an AMP video codec
module such as the microMPEG4, microMPEG-D4 or microH264-D4. The PCI
connector is also used to provide the power supply to the board. Alternatively,
input power may be connected via the screw terminal block.
Please note: mini PCI is specified for 3.3v operation only and therefore the
DVICOMP-IS is a 3.3v add-in card when used with a mini PCI module.

Ordering information
The following part number(s) can be used when ordering:
DVICOMP-IS-P PAL output
DVICOMP-IS-N NTSC/RS-170A output
DVICOMP-IS-P-EXT PAL output (-40°C to +85°C)
DVICOMP-IS-N-EXT NTSC output (-40°C to +85°C)
Cable-ST-MMCX-TO-BNC-S Composite output cable (MMCX to BNC)
Cable-STANAG/TMDS TMDS input cable (flat flex to DVI)
Anti-static handling
The board(s) supplied contain electrostatic components that are susceptible to
permanent damage from electrostatic discharge (static electricity). To prevent
electrostatic discharge, the boards are supplied in anti-static packaging.
When handling a board, observe the following anti-static precautions to alleviate
risk of damage:
▪Remove the board(s) from the packaging only when you are working on an
anti-static, earthed surface and wearing an anti-static wrist strap.
▪Retain the anti-static packaging that the board(s) were supplied in. If you
remove a board from a system, store it in this packaging.
RoHS compliance
The European RoHS Directive (Restriction on the use of certain Hazardous
Substances –Directive 2002/95/EC) limits the amount of six specific substances
within the composition of the product. The DVICOMP-IS is RoHS compliant.

PCI1 - PC/104 -Plus bus.
Standard 32-bit PCI-104 bus PCI Rev 2.1 compliant, 3.3V operation.
The standard PCI bus signals are only connected to the mini PCI socket. Since
mini PCI is defined as 3.3v only (not 5v compliant), the DVICOMP-IS may only
serve as a 3.3v Add-in card when fitted with a module.
MINI1- mini PCI Type III 32-bit PCI (3.3V operation)
Standard 3.3v mini PCI bus expansion connector.
LEVEL1 –links 1-2 and 3-4
Used for IDSEL card selection.
The setting of the first two links on the LEVEL header determine the logical stack
position of the DVICOMP-IS on the PCI-104 stack. This setting routes the
appropriate IDSEL, PCICLK, REQ and GNT signals to the mini PCI card hosted on
the DVICOMP-IS card.

Cable set
The DVICOMP-IS may be supplied with a DVI breakout board that plugs into the
TMDS connector via a flat flex cable (part CABLE-STANAG/TMDS).
A composite output cable may also be included in the form of a BNC to MMCX co-
axial lead (part CABLE-ST-MMCX-TO-BNC-S). The MMCX connector interfaces
with the COMP header on the board.
