Outputs
Video
2 channel Serial Digital Component (SDI) 270Mbit to EBU 3267-E &
SMPTE 259M (Audio is embedded to SMPTE or SONY format) - Two
buffered outputs are available for each TANDEM-110 channel with
suitable rear connectors
Output return loss >15db at 270Mbs
Audio
Dependent on sub-modules fitted
SDI embedded to SMPTE272M-A
Monitoring
1 x miniature front mounted audio jack and switch selects individual
stereo audio analogue monitoring on both embedder and de-embedder
Also available on rear connector
Crystal oscillator
Free running SDI signal can be maintained at embedder output to support
extended video loss and to allow an SDI transport for continuous
AES/EBU output at all times
Embed/de-embedder
timing
Inter-channel variation: 1 clock cycle
AES/EBU digital audio time delay format dependent – Side1 to Side 2
delay round-trip varies from 310µs to 835µs
Analogue audio time delay format dependent – Side1 to Side2 round trip
delay varies from 1,540µs to 2,075µs
SDI video delay 400 clock cycles at 270MHz or 1.481µs
Note:
Round trip audio delay measured by taking de-embedded audio
output from one side, and re-embedding into other side.
De-embedding format
Automatic selection of SMPTE or SONY formats or manual selection
