CL-C3

• 1000 x 1 x 8-bit

• 2 channel digital video output (RS-422)

• DCF configured for 480 lines per virtual frame

• line scan rate is variable and is controlled by external trigger signal

• Matrox Pulsar receiving TTL external trigger

• Matrox Pulsar sending EXPOSURE1 (PRIN), EXPOSURE2 (EXSYNC) and reference

EXSYNC

MCLK

STROBE

LVAL

TTL external trigger

Matrox Pulsar

(with PULSAR/DIG/MOD)

clock (MCLK) signals (all RS-422) to camera; the EXPOSURE1 and EXPOSURE2
signals control the exposure time

• Matrox Pulsar receiving RS-422 pixel clock (STROBE @ 7.159MHz) and RS-422

vsync (LVAL) signals from camera; the LVAL signal initiates line readout

• DCF used: CLC3_LS.DCF

• in addition to the DCF, PSG FPGA version 3.01 or newer is required; if this version is

not on your release of the MIL driver for Pulsar, the newest version can be found on the
BBS or at the FTP site

Cabling
Requirements

Variable line scan rate

• IMG-7W2-TO-5BNC cable required for TTL external trigger source and

PULSAR/DIG/MOD required for digital data, syncs and control signals in RS-422
format
