11.3 Voice Port Functional Timing Diagrams
Figure 11-16. Transmit Voice Port Interface with PCM Octets
Figure 11-17 shows the receive serial port timing relationship when the data stream contains PCM octets. This
example shows two PCM octets being demuxed from the Ethernet data. RVSYNC is minimum one clock period
wide, but may be high multiple clock periods. Note that the PCM octets output on RVDATA are buffered for one
RVSYNC period, i.e. the PCM octets are delayed one frame. Voice data may be output at any point between frame
syncs, output when RVDEN is low.
