TP3067BN Datasheet PDF - TI

●description

●The TP3064B, TP3067B, TP13064B, and TP13067B each comprise a single-chip pulse code-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 compatible

●Complete PCM Codec and Filtering Systems Include:

●– Transmit High-Pass and Low-Pass Filtering

●– Receive Low-Pass Filter With (sin x)/x Correction

●– Active RC Noise Filters

●– µ-Law or A-Law Compatible Coder and Decoder

●– Internal Precision Voltage Reference

●– Serial I/O Interface

●– Internal Autozero Circuitry

●µ-Law – TP13064B and TP3064B

●A-Law – TP13067B and TP3067B
