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
