TP3057BDW Description

Short technical summary and product information.

The Texas Instruments TP3057BDW is a monolithic serial interface IC that combines a PCM codec and filter. This device is designed to interface a full-duplex voice telephone circuit with a TDM system. It includes transmit high-pass and low-pass filtering, receive low-pass filter with (sin x)/x correction, and active RC noise filters.

 

The TP3057BDW features a μ-Law or A-Law compatible coder and decoder, an internal precision voltage reference, and an internal autozero circuitry. It operates on ±5V power supply with low operating power consumption of typically 50mW and a power-down standby mode of typically 3mW. The digital interface is TTL- or CMOS-compatible.

 

This codec and filter IC is intended for use at the analog termination of a PCM line or trunk. It requires two transmit and receive master clocks and data clocks, along with transmit and receive frame-sync pulses. The device is characterized for operation from 0°C to 70°C.

 

The TP3057BDW is supplied in a 16-SOIC Surface Mount package, maximizing line interface card circuit density. It is an improved version of National Semiconductor's TP3057 and TP3057-X devices.
