S/PDIF Input/Output

S/PDIF Input/Output

An S/PDIF output is available for connection with an external A/V decoder/amplifier.

The signal on this S/PDIF output is selected by an on chip Multiplexer between the internal signal

and an external signal present on S/PDIF bypass input (Pin 44) with SPDIF_MUX bit in the

DAC_CONTROL register.

The outputted internal signal can be selected from:

● L/R

● C/Subwoofer

● HP or Surround L/R

● SCART L/R

The external signal is for example the signal provided by an external Dolby

® Digital decoder

(STD2000).

Mute facility is also provided on the S/PDIF output.

Note:

The S/PDIF_IN pin (Pin 44) is a CMOS digital pin and input signals on this pin must fulfill the

characteristics as mentioned in Section 13.12: Digital I/Os Characteristics on page 144 (±0.5 VPP

standard S/PDIF input level is not directly supported by the device and needs external circuitry).
