DESCRIPTION
The TS5070series are the second generationcom-
bined PCM CODEC and Filter devices optimized
for digital switching applications on subscriber and
trunk line cards.
Using advanced switched capacitor techniques the
TS5070 and TS5071 combine transmit bandpass
and receive lowpass channel filters with a com-
panding PCM encoder and decoder. The devices
are A-law and -law selectable and employ a con-
ventional serial PCM interface capable of being
clocked up to 4.096 MHz. A number of programma-
ble functions may be controlled via a serial control
port.

PROGRAMMABLE CODEC/FILTER
Channel gains are programmable over a 25.4 dB
range in each direction, and a programmable filter
is included to enable Hybrid Balancing to be ad-
justed to suit a wide range of loop impedance con-
ditions.
Both transformer and active SLIC interface circuits
with real or complex termination impedances can
be balanced by this filter, with cancellation in ex-
cess of 30 dB being readily achievable when meas-
ured across the passbandagainst standardtest ter-
mination networks.
To enable COMBO IIG to interface to the SLIC con-
trol leads, a number of programmable latches are
included ; each may be configured as either an in-
put or an output. The TS5070 provides 6 latches
and the TS5071 5 latches.
