DS2176数据手册集成电路（IC）的电信规格书PDF

描述 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 that 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-pin package. Application areas include digital trunks, drop and insert equipment, transcoders, digital cross-connects (DAC), private network equipment, and PABX-to-computer interfaces such as DMI and CPI.
