The 73M1903 is a single-chip analog front end (AFE) that’s ideal for DSP or
RISC-based soft modem applications such as fax and multi-function peripherals
(MFPs), game consoles, Internet appliances, and set-top boxes. It offers a
complete array of features designed to reduce the external component count.
Reduced Component Count
The device eliminates the need for a dedicated crystal oscillator with a flexible
PLL, a 16-bit CODEC, differential hybrid circuitry, GPIO pins, and integrated
DAA control.
Programmable Sample Rates
The 73M1903 can be programmed for various sample rates support modem
standards operating at speeds from 600bps to 56Kbps.
Pin Compatible with 73M2901CL
A distinctive feature of this device is its pin compatibility with TDK's flagship
V.22bis hard modem, the 73M2901CL. It also has the ability to support third
party high speed data pumps on the same PCB. This offers customers a cost
effective method to configure low and high-speed modem solutions in the same
system as well as a risk-free migration path from hard to soft modems.
Fully Differential Hybrid Circuitry
Having fully differential hybrid circuitry improves signal-to-noise ratio
performance under low receive level conditions, and ensures compatibility with
any standard transformer-based DAA. On-chip registers facilitate management
of DAA functions including parallel pick-up, ring detection, caller ID, and hook
control through the same serial port used for data.
Flexible DAA Configuration
The device can be configured for FCC, CTR-21 and other worldwide
telecommunications standards, and operates at speeds of 600bps to 56Kbps. It
also supports two power conservation operating modes and seven test modes.
TDK Semiconductor's expertise in analog and mixed-signal technology has
made it possible to develop a very flexible and yet cost-effective AFE
companion to RISC processors or DSPs in embedded communications
applications.
