TP3070, TP3071, TP3070-X BO II Programmable PCM CODEC/Filter April 1994 TP3070, TP3071, TP3070-X BO ® II Programmable PCM CODEC/Filter General Description The TP3070 and TP3071 are second-generation bined PCM CODEC and Filter devices optimized for digital switching applications on subscriber line and trunk cards. Using advanced switched capacitor techniques, BO II bines transmit bandpass and receive lowpass channel filters with a panding 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....
