This module can be mounted in a GeckoFlex
frame when ordered with the 8900V-R GeckoFlex
Video rear module.
8941
Component digital monitoring distribution amplifier
The 8941 monitoring DA supports up to four
NTSC or PAL encoded monitor outputs for
picture viewing, in addition to four reclocked
serial component digital outputs. The 8941
is tailored specifically for 270 Mb/s serial
component digital signals, both 525 and 625
formats. In addition to a composite video
monitoring output, the 8941 also indicates via
front panel LED whether either ancillary data or
audio is embedded in the signal.
