... W681360 is a single-rail, single channel PCM CODEC for voiceband applications. The CODEC complies with the specifications of the ITU-T G.712 recommendation. The CODEC block diagram in Section 3 illustrates the main components of the W681360. The chip consists of a PCM interface, which can process long and short frame sync formats. The pre-scaler of the chip provides the internal clock signals and synchronizes the CODEC sample rate with the external frame sync frequency ...

... Receive Gain Adjust Mode The W681360 can be put in the receive path adjust mode by applying a logic “1” to the BCLKR pin while all other clocks are clocked normally. The device is then in a position to read 16-bits of data, with three additional coefficient bits an addend to the 13-bit digital voice data. These three coefficients are used to program a receive path attenuation, thereby allowing the receive signal to be attenuated according to the values in the following table ...

... The data transmit pin PCMT will go back to the high impedance state halfway through the LSB. The Short Frame Sync operation of the W681360 is based on a 13-bit data word. When receiving data on the PCMR pin, the data is clocked in on the first falling edge after the falling edge that coincides with the Frame Sync signal ...

... LOW for the entire frame sync period while the MCLK and BCLK pin clock signals are still present, the W681360 will enter the low power standby mode. Another way to power down is to set the PUI pin to LOW. When the system needs to be powered up again, the PUI pin needs to be set to HIGH and the transmit Frame Sync pulse needs to be present ...
