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-

justed to suit a wide range of loop impedancecon-

ditions.

Both transformerand active SLIC interfacecircuits

with real or complex termination impedances can

be balanced by this filter, with cancellation in ex-

cessof 30 dB beingreadilyachievablewhenmeas-

mination networks.

DESCRIPTION

TheTS5070series arethesecondgenerationcom-

bined PCM CODEC and Filter devices optimized

for digital switching applicationson subscriberand

trunk line cards.

Using advancedswitchedcapacitortechniquesthe

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 µ-law selectable and employ a con-

ventional serial PCM interface capable of being

clockedup to 4.096MHz.A number ofprogramma-

ble functionsmay be controlled via a serial control

port.

To enableCOMBOIIG tointerfaceto theSLICcon-

trol leads, a number of programmable latches are

included ; each may be configuredas either an in-

put or an output. The TS5070 provides 6 latches

and the TS5071 5 latches.
