TP3094 COMBO® Quad PCM Codec/Filter
The TP3094 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
device 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.
The TP3094 includes a flexible PCM digital interface,
which allows the device to be connected to
PCM busses of different formats. It can also be
connected with other TP3094 devices in a cascade
fashion, for a system with up to 128 POTS
interfaces (when a 2.048MHz PCM bus is used).
