73M1903 Datasheet | TDK Semiconductor

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. 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...
