Product Summary
The TP3094V/NOPB is a monolithic PCM Codec and Filter device implemented using a digital signal processing architecture. It provides four voice channels, combining transmit bandpass and receive low pass channel filters with companding Alaw or m-law PCM encoders and decoders. The TP3094V/NOPB is fabricated using National’s advanced CMOS process. The device includes anti-aliasing filters and sigma-delta converters dedicated to each channel, and by a common signal processing unit which performs all the remaining filtering and processing for the four channels.
