GENERAL DESCRIPTION
The XR-T5683A is a PCM line interface chip consisting of
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
attenuated by -10dB cable loss at one-half the bit rate. At
nominal supply voltage operation, the typical current
consumption is 40mA.
