Product Description

The BTK1A and BTM1A devices are dual differential transceiver circuits that transmit and receive digital data over balanced transmission lines and are compatible with Agere Systems Inc. quad differential drivers and receivers. The dual drivers translate input TTL logic levels to differential pseudo-ECL output levels. The dual receivers convert differential input logic levels to TTL output levels. Each driver/receiver pair has its own common enable control allowing serial data and a control clock to be transmitted and received on a single integrated circuit. The BTK1A transceiver requires the customer to supply termination resistors on the circuit board.
