VSM-6802 Digital Composite Video
Signal Monitor Module
Overview
The VSM-6802 is a monitoring quality digital-to-analog converter for
serial digital 4 fsc NTSC signals (4fsc PAL-B signals are not supported).
This module has one serial digital input and provides four reclocked
serial digital and four composite analog outputs.
Any ancillary data is removed from the digital signal, and synchronizing
pulses are returned to RS-170A specifications before the composite
video is converted to analog.
Specifications and designs are subject to change without notice.
