Product Summary

The AFE1104E is an Analog Front End. The AFE1104E reduces the size and cost of an HDSL or MDSL system by providing all of the active analog circuitry needed to connect PairGain Technologies SPAROW HDSL digital signal processor to an external compromise hybrid and a 1:2 HDSL line transformer. All internal filter responses as well as the pulse former output scale with clock frequency—allowing the AFE1104 to operate over a range of bit rates from 196kbps to 1.168Mbps. The receive section filters and digitizes the symbol data received on the telephone line and passes it to the SPAROW. The HDSL Analog Interface is a monolithic device fabricated on 0.6mCMOS. It operates on a single +5V supply. The AFE1104E is housed in a 48-pin SSOP package.
