Interfaces to parallel or serial backplanes
Extracts and buffers robbed–bit signalling
Inhibits signalling updates during alarm or slip condi-
tions
Integration feature “debounces” signalling
Slip–compensated output indicates when signalling
updates occur
Compatible with DS2180A T1 Transceiver
Surface mount package available, designated

DESCRIPTION
The DS2176 is a low–power CMOS device specifically
designed for synchronizing receive side loop–timed T–
carrier data streams with system side timing. The de-
vice has several flexible operating modes which simplify
interfacing incoming data to parallel and serial TDM
backplanes. The device extracts, buffers and integrates
ABCD signalling; signalling updates are prohibited dur-
ing alarm or slip conditions. The buffer replaces exten-
sive hardware in existing applications with one “skinny”
24–lead package. Application areas include digital
trunks, drop and insert equipment, transcoders, digital
cross–connects (DACS), private network equipment
and PABX–to–computer interfaces such as DMI and
CPI.
