DESCRIPTION
TheTS5070seriesarethesecondgenerationcom-
bined PCM CODEC and Filter devices optimized
for digital switching applicationson subscriberand
trunkline cards.
Usingadvancedswitchedcapacitortechniquesthe
TS5070 and TS5071 combine transmit bandpass
and receive lowpass channel filters with a com-
panding PCM encoder and decoder. The devices
are A-lawand
μ
-law selectableand employ a con-
ventional serial PCM interface capable of being
clockedup to 4.096MHz.Anumberofprogramma-
ble functionsmay be controlled via a serial control
port.
Channel gains are programmable over a 25.4 dB
range in each direction, and a programmablefilter
is included to enable Hybrid Balancing to be ad-
justedto suita widerange of loop impedancecon-
ditions.
Both transformerand activeSLIC interfacecircuits
with real or complex terminationimpedances can
be balanced by this filter, with cancellation in ex-
cessof 30dBbeingreadilyachievablewhenmeas-
uredacrossthepassbandagainststandardtestter-
mination networks.
ToenableCOMBOIIGtointerfaceto theSLICcon-
trol leads, a number of programmablelatches are
included ; each may be configuredas eitheran in-
put or an output. The TS5070 provides 6 latches
and the TS5071 5 latches.
