Description

The MH89101 is a thick film hybrid device which is used in conjunction with the MT8910 to perform two to four wire conversion and analog signal conditioning on the received 2B1Q signal.

The signal conditioning is necessary to enable the DSLIC to interface to the Digital Subscriber Line as defined in ANSI T1.601-1988. The precanceller block will perform two to four wire conversion and provide adequate isolation between transmit and receive paths.

The small size and the precise resistor matching on the hybrid makes MH89101 suitable for line card or terminals which use the MT8910 2B1Q U-Interface Transceiver.
