Overview
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 compatibility with any standard transformer intended for PSTN communications applications.
The device incorporates a programmable sample rate circuit to support soft modem and DSP based implementations of all speeds up to V.
92 (56Kbps).
The sampling rates supported are from ...
