XRT56L85P Datasheet PDF - Exar Corporation

GENERAL DESCRIPTION
The XRT56L85 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.

FEATURES
● Low Power (Typical 14mA)
● Single +5V Supply
● Up to 2.048 Mbps Operation in Both TX and RX Directions
● Receiver Input can be:
    Balanced Transformer Coupled
    Capacitively (Twisted Pair)
    Single Coaxial Capacitive Coupling

APPLICATIONS
● T1 and CEPT Interfaces
● CPI
● DMI
