‘‘Enhanced’’ Serial Interface

CMOS CODEC/Filter COMBO

General Description

The TP3064 (m-law) and TP3067 (A-law) are monolithic

PCM CODEC/Filters utilizing the A/D and D/A conversion

architecture shown in Figure 1, and a serial PCM interface.

The devices are fabricated using National’s advanced dou-

ble-poly CMOS process (microCMOS).

Features

Complete CODEC and filtering system including:

Ð Transmit high-pass and low-pass filtering

Ð Receive low-pass filter with sin x/x correction

Ð Active RC noise filters

Ð m-law or A-law compatible COder and DECoder

Ð Internal precision voltage reference

Ð Serial I/O interface

Ð Internal auto-zero circuitry

Ð Receive push-pull power amplifiers

m-lawÐTP3064

Similar to the TP305X family, these devices feature an addi-

tional Receive Power Amplifier to provide push-pull bal-

anced output drive capability. The receive gain can be ad-

justed by means of two external resistors for an output level

of up to 6.6V across a balanced 600X load.

A-lawÐTP3067

Also included is an Analog Loopback switch and a TS out-

put.

Designed for D3/D4 and CCITT applications

5V operation

See also AN-370, ‘‘Techniques for Designing with CODEC/

Filter COMBO Circuits.’’

Low operating powerÐtypically 70 mW

Power-down standby modeÐtypically 3 mW

Automatic power-down

TTL or CMOS compatible digital interfaces

Maximizes line interface card circuit density
