PCM3052A

SLES160 – NOVEMBER 2005

Digital audio data is interfaced to the PCM3052A on LRCK (pin 10), BCK (pin 11), DIN (pin 12), DOUT (pin 13),

and DOUTS (pin 14). The PCM3052A can accept 24-bit I2S format only. In case of AC-3 type output data for

DOUTS, bits 17 to 24 of DIN must be held LOW. See the Digital Audio Interface Transmitter (DIT) section of this

data sheet.

The PCM3052A accepts only 64 clocks of BCK during one clock of LRCK. Figure 46 and Figure 47 illustrate

audio data input/output format and timing.
