MH89626C General Description
The MH89626C SLIC provides all of the functions required to interface 2-wire off premise subscriber loops to a serial TDM, PCM, switching network of a modern PBX. The MH89626C is manufactured using thick film hybrid technology which offers high voltage capability, reliability and high density resulting in significant printed circuit board area saving of the line cards. A complete line card can be implemented with very few external components.
The SLIC has a simple serial control interface to control the receive gain setting, relay drivers for ringing, and Tip/Ring reversal for DID operation.
