GENERAL DESCRIPTION
The XR-T5683A is a PCM line interface chip consisting of attenuated by -10dB cable loss at one-half the bit rate. At
both transmit and receive circuitry. This device is offered
in a plastic dual in-line (PDIP) or in a surface mount
package (SOIC). The maximum bit rate of the chip is
8.448Mbps, and the signal level to the receiver can be
nominal supply voltage operation, the typical current
consumption is 40mA.
