DS2175N

T1/CEPT Elastic Store


Please check latest availability status for a specific part variant.

Description

The DS2175 is a low-power CMOS elastic-store memory optimized for use in primary rate telecommunications transmission equipment. The device serves as a synchronizing element between async data streams and is compatible with North American (T1-1.544MHz) and European (CEPT-2.048MHz) rate networks. The chip has several flexible operating modes which eliminate support logic and hardware currently required to interconnect parallel or serial TDM backplanes. Application areas include digital trunks, drop and insert equipment, digital cross-connects (DCC), private network equipment, and PABX-to-computer interfaces such as DMI and CPI.
