Frame Sync input: This signal is a 8 16kHz clock which defines the start of the
transmit and receive frames. Any of three formats may be used for this signal: non
delayed normal mode, delayed mode, and non delayed reverse mode.
Master Clock Input for Voice Mode. Can also be used as Master Clock in Tone Only
and FM Modes. The allowed clock frequencies are 512 kHz, 1.536 MHz, 2.048 MHz
or 2.56 MHz. MCLK is the Voice Data Clock.
Auxiliary Clock Input. Can be used as Master Clock in Tone Only and FM Modes.
Allowed clock frequencies are 512kHz, 1.536MHz, 2.048MHz or 2.56MHz.
Do Not Connect. This pin must be left unconnected.
A capacitor must be connected between this node and Ground.
Power supply input for the analog section. VCC and VCCA can be directly connected
together for low cost applications.
Analog Ground: All analog signals are referenced to this pin. GND and GNDA can be
connected together for low cost applications.
Power supply input for the output drivers. VCCP and VCCA must be connected
together.
Power ground. Output drivers are referenced to this pin. GNDP and GNDA must be
connected together.
Analog Ground connection. GNDCM can be connected to GNDA.
Power supply input for the digital section.
Power supply Input for the Digital I O pins.
Ground for the digital section
