MCDA-204 WC106 BLOCK DIAGRAM
Input processing includes transformer isolation, cable termination, cable equalization, and AES digital
audio interface receiver (DIR) and digital audio interface transmission (DIT). The output of each input
signal processor is routed to a multiplexing chip which allows connection to each of the three output
groups. Selection is controlled by the position of the configuration switches on the back panel of the
MCDA. Each output port is driven by its own driver preventing interaction between outputs. Two
separate highly accurate crystal clock sources allow the MCDA to achieve frame rates accurate to less
than 1 part per million. A microprocessor sets up the MCDA for operation.
Super Word Clock is a bit clock like signal that is exactly 256 times the frequency of the associated
frame rate for sample rates up to 96 k samples per second or 128 times for rates above 96 k samples.
