XR-T5680

XR-T5680 PCM Line Interface Chip GENERAL DESCRIPTION The XR-T5680 is a PCM line interface chip. It consists of both transmit and receive circuitry in a OIL 18 pin package. The maximum bit rate the chip can handle is 10 M Bits/s and the signal level to the receiver can be attenuated by -10 dB cable loss at half the bit rate. Total current consumption is between 27-46 mA at +5.0 V.
