73M1903 - Modem Analog Front End
The TDK 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 design of
73M1903 Features
* of the device include an input reference frequency circuit, which accepts a range of crystals from 9-27MHz. It also accepts external reference clock values between 9-40MHz generated by the host processor. In most applications, this eliminates the need for a dedicated crystal oscillator and reduces t
