7.4 S/PDIF Audio Interface

This S/PDIF interface supports the IEC60958 standard. This is a serial unidirectional self-

clocking interface. The interface supports linear PCM sampling rates of 32 kHz, 44.1 kHz, 48

kHz, 96 kHz, and 192 kHz with 24-bit stereo data samples.

Notes:

• All traces impedance required to be 55 Ω+/- 10%.

• All signals prefer to reference to ground plane and routed over a continuous plane.

• Simulation data based on Cin = 10pF (no IBIS models).
