Description

The DS2175 is a lowpower CMOS elasticstore memory optimized for use in primary rate telecommu-nications transmission equipment. The device serves as a synchronizing element between async datastreams and is compatible with North American (T11.544 MHz) and European (CEPT2.048 MHz) ratenetworks. The chip has several flexible operating modes which eliminate support logic and hardware cur-rently required to interconnect parallel or serial TDM backplanes. Application areas include digitaltrunks, drop and insert equipment, digital crossconnects (DACS), private network equipment andPABXtocomputer interfaces such as DMI and CPI.
