4.9.2 SPDIF timing parameters

The Sony/Philips Digital Interconnect Format (SPDIF) data is sent using the bi-phase marking code. When encoding, the SPDIF

data signal is modulated by a clock that is twice the bit rate of the data signal.

The following table and figures show SPDIF timing parameters for the Sony/Philips Digital Interconnect Format (SPDIF), including

the timing of the modulating Rx clock (SPDIF_SR_CLK) for SPDIF in Rx mode and the timing of the modulating Tx clock

(SPDIF_ST_CLK) for SPDIF in Tx mode.

The DSE[5:0] = 001111 and FSEL1[1:0] = 11 are required drive settings to meet the timing.
