SEEQ - invalid (SEEQ Technologies Inc. ) : 93C95

ATM 25.6 MB Transceiver and Data Recovery

The 93C95 is a highly integrated analog interface IC for twisted pair25.6 Mbps ATM.T he 93C95 consists of transmitter with wave shaping and on chip filters,twisted pair receiver with on chip adaptive equalizer and filters, clockand data recovery, digital interface and serial port.The addition of internal output waveshaping circuitry and on-chip filters eliminates the need for external filters and common mode chokesnormally required in these applications.The 93C95 can access three registers through the serial port. These registers contain configuration inputs and status outputs.The 93C95 is ideal as a media interface for ATM25 adapter cards and hubs.
