MH89790B General Description


The MH89790B is Mitel's CEPT PCM 30 interface solution, designed to meet the latest CCITT standards PCM 30 format with CRC-4. The MH89790B provides a complete interface between a 2.048 Mbit/sec digital trunk and Mitel's Serial Telecom Bus, the ST-BUS.

The MH89790B is a pin-compatible enhancement of the MH89790, permitting the removal of the tuneable inductor and inclusion of the external NAND gate used for generating RxD.
