TP3064B
description
The TP3064B, TP3067B, TP13064B, and TP13067B each prise a single-chip pulsecode-modulation encoder and decoder (PCM codec), and PCM line filter. They also provide band-pass filtering of the analog signals prior to the encoding, and low-pass filtering after the decoding of voice signals and call-progress tones. All the functions required to interface a full-duplex (2-wire) voice telephone circuit with a time-division-multiplexed (TDM) system are included on-chip. These devices are pin-for-pin patible with the National Semiconductor TP3064 and TP3067. Primary applications include:
- Line interface for digital transmission and switching of T1 carrier, PABX (private automated branch exchange), and central office telephone systems
- Subscriber line concentrators
- Digital-encryption systems
- Digital voice-band data-storage systems
- Digital signal processing
