73M1903 Datasheet - Teridian Semiconductor

73M1903 - Modem Analog Front-End

The Teridian 73M1903 Analog Front End (AFE) IC includes fully differential hybrid driver outputs, which connect to the telephone line interface through a transformer-based DAA.

The receive pins are also fully differential for maximum flexibility and performance.

This arrangement allows for the desig

73M1903 Features

* of the device include an input reference frequency circuit, which accepts a range of crystals from 9-27 MHz. It also accepts external reference clock values between 9-40 MHz generated by the host processor. In most applications, this eliminates the need for a dedicated crystal oscillator and reduces
