D to A Output Module (Optional)
The optional D to A Output module is an 8 output board that replaces a “standard” 8 output
HD/SD board.
This board will take a valid 270 Mbps 525 or 625 digital video signal and output a valid NTSC or
PAL composite video signal.
There are 8 D to A converters on each board and each of them operates independently.
Each output will automatically detect the incoming signal format (525 or 625) and output the
corresponding composite output (NTSC or PAL).
The performance specifications are:
Return loss: <-30 db @ 5 MHz
Differential gain: +/- 0.3 percent @ 3.58 MHz or 4.443 MHz
Differential phase: +/- 0.5 degrees @ 3.58 MHz or 4.443 MHz
