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.
