Type definitions:

AI - Analog input, AO - Analog Output, DI - Digital Input, DO - Digital output, DOT - Digital Output Tristate,

DIO - Digital Input Output Open Drain, P - Power Supply or Ground.

B5

FS

DI

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.

A4

MCLK

DI

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.

C5

AUXCLK

DI

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.

E4

DNC

AI

Do Not Connect. This pin must be left unconnected.

C3

CAP2

AI

A capacitor must be connected between this node and Ground.

C2

VCCA

P

Power supply input for the analog section. VCC and VCCA can be directly connected

together for low cost applications.

D1

GNDA

P

Analog Ground: All analog signals are referenced to this pin. GND and GNDA can be

connected together for low cost applications.

F3

VCCP

P

Power supply input for the output drivers. VCCP and VCCA must be connected

together.

E3

GNDP

P

Power ground. Output drivers are referenced to this pin. GNDP and GNDA must be

connected together.

D3

GNDCM

P

Analog Ground connection. GNDCM can be connected to GNDA.

B4

VCC

P

Power supply input for the digital section.

B6

GND

P

Ground for the digital section

D4

VCCIO

P

Power supply Input for the Digital I

⁄ O pins.
