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 with the National Semiconductor TP3064 and TP3067. Primary applications include: VPO+ ANLG GND VPO – VPI VFRO VCC FSR DR BCLKR/CLKSEL MCLKR/P……
