Description

Burr-Brown's Analog Front End greatly reduces the size and cost of an HDSL or MDSL system by providing all of the AFE1104 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. Functionally, this AFE1104  unit is separated into a transmit and a receive section. The transmit section generates, filters, and buffers outgoing 2B1Q data. 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. It is housed in a 48-pin SSOP package.
