or 0.26UI pk-pk (1 UI = 1/128 Fs ). For a particular Fs , the max jitter is shown in
Table
Table 2: Input Jitter for Different Sample Rates
The SPDIF Input receiver will reproduce the input data and clock without error if the
maximum input jitter remains within the specified max jitter tolerance above. The
receiver design meets and exceeds the IEC60958-3 consumer jitter requirements
specification (i.e 0.25 UI pk-pk between 200 Hz and 400 kHz jitter freq. ).
The oversampling clock supplied to the input receiver is derived from a divider in the
central clock control block. The divider value to select is determined by
the oversampling clock has been selected by programming a divider value, the
condition of the LOCK bit status indicator in SPDI_STATUS provides feedback on
whether the selected oversampling clock has allowed the interface to achieve lock
onto the incoming SPDIF input stream. The settings provided by the divider for the
oversampling clock are sufficient for capture of 32 kHz, 44.1 kHz, 48 kHz and 96 kHz
sample rate input streams.
The S/PDIF register set is outlined in
