General Description

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 a high performance hybrid circuit to improve signal to noise performance under low receive level conditions, and patibility with any standard transformer intended for PSTN munications applications.

Key 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.
