描述 Description

The XRT6165 is a CMOS device which contains the digital circuitry necessary to interface both directions of a 64kbps data stream to 2.048Mbps transmit and receive PCM time-slots. The XRT6165 and the companion XRT6164 line interface chip together form a CCITT G.703 compliant 64kbps codirectional interface.
The XRT6165 contains separate transmit and receive sections. The transmitter transforms 8-bit serial data from a 2.048Mbps time-slot into an encoded 64kbps data stream. The receiver, which performs the reverse operation, decodes the 64Kbps data, extracts a clock signal, and then outputs the data to a 2.048Mbps time-slot. The XRT6165 provides features which allow the repetitions and deletions of both received and transmitted data as clock skews and transients occur.
