TP13054B General Description

The TP3054B, TP3057B, TP13054B, and
TP13057B 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-divisio -multiplexed) system. These devices are pin-for-pin compatible with the National Semiconductor TP3054B and TP3057B, respectively. Primary applications include:
• 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 TP3054B, TP3057B, TP13054B, and TP13057B provide the band-pass filtering of the analog signals prior to encoding and after decoding of voice and call progress tones. The TP3054B and TP13054B 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 TP3054B and TP3057B are characterized for operation from 0°C to 70°C. The TP13054B and TP13057B are characterized for operation from 40°C to 85°C
