TP11362A

Quad Adaptive Differential PCM Processor

General Description

Features

n CCITT G.726 compatible at 40, 32, 24, 16 kbps

n ANSI T1.301 compatible at 32 kbps

n 8-channel half-duplex (encode or decode) or 4-channel

full-duplex operation in 8 kHz frame

The TP11362A is a quad (4) channel Adaptive Differential

Pulse Code Modulation (ADPCM) transcoder, fully compat-

ible to ITU G.726 recommendation in 40 kbps, 32 kbps,

24 kbps, 16 kbps and ANSI 32 kbps modes. The TP11362A

ADPCM processor can operate on up to 8 independent

channels in an 8 kHz frame. Each channel is individually

configured, supporting both full and half duplex operation. All

input/output transfers occur on an interrupt basis using se-

rial, double buffered data registers. Together with National’s

TP3054/57 COMBO^®or TP3070/71 COMBO II devices, the

TP11362A forms complete ADPCM channels with Codec/

filtering.

n Each channel individually configurable

n Selectable µ-law or A-law PCM coding

n Asynchronous 8 MHz master clock operation

n TTL and CMOS compatible inputs and outputs

n 28-pin PLCC or 24-pin DIP packages

n Power consumption of typ. 6 mW at +5V per full-duplex

channel

n On-Chip Power-On-Reset

n −40˚C to +85˚C operating temperature range

n Single 5V supply
