conditions
§ Integration feature “debounces” signaling
§ Slip–compensated output indicates when
signaling updates occur

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 device has several flexible operating modes
which simplify interfacing incoming data to parallel and serial TDM backplanes. The device extracts,
buffers and integrates ABCD signaling; signaling updates are prohibited during alarm or slip conditions.
The buffer replaces extensive 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.
