description

DW OR N PACKAGE

(TOP VIEW)

The TP3054A, TP3057A, TP13054A, and

TP13057A are comprised of a single-chip PCM

codec (pulse code-modulated encoder and

decoder) and PCM line filter. These devices

provide all the functions required to interface a

full-duplex (2-wire) voice telephone circuit with a

TDM (time-division-multiplexed) system. These

devices are pin-for-pin compatible with the

National Semiconductor TP3054A and TP3057A,

respectively. Primary applications include:

VFXI+

VFXI–

GSX

ANLG GND

VFRO

TSX

FSX

FSR

BCLKX

MCLKX

BCLKR/CLKSEL

MCLKR/PDN

•

Line interface for digital transmission and

switching of T1 carrier, PABX, and central

office telephone systems

•

Subscriber line concentrators

Digital-encryption systems

Digital voice-band data-storage systems

Digital signal processing

These devices are designed to perform the transmit encoding (A/D conversion) and receive decoding (D/A

conversion) as well as the transmit and receive filtering functions in a PCM system. They are intended to be

used at the analog termination of a PCM line or trunk. The devices require two transmit and receive master

clocks that may be asynchronous (1.536 MHz, 1.544 MHz, or 2.048 MHz), transmit and receive data clocks that

are synchronous with the master clock (but can vary from 64 kHz to 2.048 MHz), and transmit and receive

frame-sync pulses. The TP3054A, TP3057A, TP13054A, and TP13057A provide the band-pass filtering of the

analog signals prior to encoding and after decoding of voice and call progress tones. The TP3057A and

TP13057A contain patented circuitry to achieve low transmit channel idle noise and are not recommended for

applications in which the composite signals on the transmit side are below –55 dBm0.

The TP3054A and TP3057A are characterized for operation from 0°C to 70°C. The TP13054A and TP13057A

are characterized for operation from –40°C to 85°C.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
