4.1.1 HW 1.1 enhancements
Extra VCXO to allow input locking independant of output frequency. This gives the following:-
• Wider input jitter tolerance.
• Master mode module will de-multiplex audio to its AES outputs regardless of loop status.
i.e. System is more resiliant as a module may fail but the remaining chains of modules
still present will still work.
• More stable frequency of SDTI as the output frequency will not change until full lock
is achieved. i.e. Downstream modules will not lose lock when an upstream module is
removed. Performance with the relay backplane is now much improved.
• Wander tolerance of Master mode module is much larger allowing the use of a loop across
video links which are time multiplexed or packetized.
