Description
The Mitel MH89793 is a low cost E1 line
driver/receiver with clock extraction requiring no
external components.
The device is suitable for both 120R and 75R
applications, by linking external pins.
By combining the MH89793 with Mitel’s E1 framer,
the MT9079, a cost effective and efficient interface to
E1 lines can be built.
