GENERAL DESCRIPTION

The XR-T56L85 is a PCM line interface chip. It consists of both transmit and receive circuitry in a DIL 18 pin package. The maximum bit rate the chip can handle is 2.048 Mbps and the signal level to the received can be attenuated by 10dB of cable loss at half the bit rate. Total current consumption is between 12-16mA at +5V.
