GENERAL DESCRIPTION
The XRT56L85is a PCMline 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.
