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.
