MSM7584D

¡ Semiconductor

PCMSO

Transmit PCM data output.

This PCM output signal is output from MSB synchronously with the rising edge of BCLK and

SYNC.

PCMSI

Transmit PCM data input.

This signal is converted to the ADPCM data. The PCM signal is shifted in on the falling edge of

BCLK. Normally, this pin is connected to PCMSO.

PCMRO

Receive PCM data output.

The PCM signal is the output signal after ADPCM decoder processing. This signal is serially

output from the MSB synchronously with the rising edge of BCLK and SYNC.

PCMRI

Receive PCM data input.

The PCM input signal is shifted in on the rising edge of BCLK input from MSB. Normally, this

pin is connected to PCMRO.

Transmit ADPCM signal output.

This signal is the output signal after ADPCM encoding, and is serially output from MSB

synchronously with the rising edge of BCLK and SYNC. This pin is an open drain output which

requires a pull-up resistor and goes to a high impedence state during power-down mode.

Receive ADPCM signal input.

Input data is shifted in serially from MSB on the rising edge of BCLK synchronously with SYNC.

BCLK

Shift clock input for the PCM data (PCMSO, PCMSI, PCMRO, PCMRI) and the ADPCM data

(IS, IR) .

The frequency ranges from 64 kHz to 2048 kHz.

SYNC

8 kHz synchronous signal input for transmit/receive PCM and ADPCM data.

This signal should be synchronous with BCLK. SYNC is used for indicating MSB of the transmit

serial PCM and ADPCM data stream.
