Features
Compatible with the MH89760B
Transmit equalizer and 6dB loop around circuit
6dB pad for easier loopback testing
Programmable for varying degrees of
equalization
Description
The MH89761 is a programmable transmit equalizer
for use with a T1 line interface, specifically the
MH89760B. The MH89761 contains a three setting
transmit equalizer, and a 6 dB pad for external loop
around. The input and output impedance of the
circuit is 100
. The device is fabricated in thick film
hybrid technology and is 2 inches high by 0.5 inches
wide. The MH89761 is designed to drive 22 gauge
twisted pair from the multiplex equipment to the
crossconnect point. Figure 1 shows how the
MH89761 is connected to the transmit side of a T1
interface.
