MH89760B General Description


The MH89760B is a complete T1 interface solution, meeting the Extended Super Frame (ESF), D3/D4 and SLC-96 formats. The MH89760B interfaces to the DS11.544 Mbit/sec digital trunk.

The MH89760B is a pin-compatible enhancement of the MH89760, permitting the removal of the tuneable inductor and inclusion of the external NAND gate used for generating RxD.
