Using advanced switched capacitor techniques the TS5070 and TS5071 combine transmit bandpass and receive lowpass channel filters with a companding PCM encoder and decoder. The devices are A-law and µ-law selectable and employ a conventional serial PCM interface capable of being clocked up to 4.096 MHz. A number of programmable functions may be controlled via a serial control port. December 1997 DIP20 (Plastic) ORDERING NUMBER: TS5071N PLCC28 ORDERING NUMBERS: TS5070FN ...
