Features

Description

• -law and A-law ITU G.711 Companding Codec

• Operates on +3.3V Power

• Differential Analog Signal Paths

• Programmable Transmit and Receive Gain, +/-12dB

in 0.1dB increments

• Transmit Path 60Hz Rejection Filter

• Differential amplifier drives +3.2dBm into 600

• Stable Gain over temperature

• PCM and IOM-2 GCI telecommunication interfaces

• Short and Long Frame Syncs Supported

• Independent Transmit and Receive Programmable

Time Slots

• Accepts PCLK from 512kHz to 8.192MHz

• SPI Serial Interface for control in PCM Mode

The CPC5750 is a voice-band CODEC with

pin-selectable PCM or IOM-2 (GCI) digital interfaces.

Clock frequencies for the PCM Mode range from

512kHz to 8.192MHz while the GCI interface allows

clocking at 2.048MHz and 4.096MHz. While the GCI

interface utilizes the integrated data link to read and

write the control registers, a four-wire Serial Peripheral

Interface (SPI) bus provides register access while in

PCM Mode.

The CODEC provides the necessary A/D and D/A

functions with pin-selectable -law or A-law

companding. A low-noise internal reference is used to

keep signal gains well controlled over supply and

temperature variations. Programmable gain of 12dB

for both transmit and receive allow the CPC5750 to

accept differential input signals as large as +8dBm,

and to source +3.2dBm differential signals into 600

while operating from a single 3.3V supply.

• Programmable Power Down Mode, I = 20A

• Analog and Digital Loopback Modes for testing
