TP3076
COMBO
II Programmable PCM CODEC/Filter for ISDN
and Digital Phone Applications
General Description
The TP3076 is a second-generation combined PCM CODEC
and Filter devices optimized for digital switching applications
on subscriber line and trunk cards and digital phone applica-
tions. Using advanced switched capacitor techniques,
COMBO II combines transmit bandpass and receive low-
pass 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 func-
tions may be controlled via a serial control port.
Channel gains are programmable over a 25.4 dB range in
each direction.
To enable COMBO II to interface to the SLIC control leads, a
number of programmable latches are included; each may be
configured as either an input or an output. The TP3076 pro-
vides 4 latches.
