DS2176

The DS2176 is a lowpower CMOS device specifically designed for synchronizing receive side looptimed Tcarrier data streams with system side timing. The device has several flexible operating modeswhich simplify interfacing incoming data to parallel and serial TDM backplanes. The device extracts,buffers andintegrates ABCD signaling; signaling updates are prohibited during alarm or slip conditions.

The buffer replaces extensive hardware in existing applications with one "skinny" 24lead package.Application areas include digital trunks, drop and insert equipment, transcoders, digitalcrossconnects(DACS), private network equipment and PABXtocomputer interfaces such as DMI and CPI.
