∗1) Power supply voltage (DVDD, RXVDD, TXVDD) is 3V. Digital and analog output terminals are free from load.
All the digital terminals except FSYNC. CLK terminal are connected to either DVDD or DVSS.
Analog terminals are connected with an appropriate resistance to TXREF or RXREF.
The soft mute is in the canceled status. (SMUTE="0")
∗2) FSYNC=8kHz, DCLK=256kHz
