73M1903
Modem Analog Front-End
Ideal AFE Solution for Cost-Sensitive Embedded Soft Modem Solutions
Part Details
- Highly Integrated AFE for Soft Modem Applications
- External DAA Circuitry is Optimized for Best Cost Structure for Single and Multiple Country PSTN Access Compliance
- Robust and Reliable Solution for Embedded Systems Designed for Normal and Extreme Environments
- Easy Path to a Soft Modem Transition
The 73M1903 is a single-chip analog front-end (AFE) device used in embedded soft modem and voice applications including high-speed data modems, satellite set-top boxes, POS terminals, MFP and fax terminals, and IP phones. This device offers multiple features designed to reduce the external component count and deliver robust performance with a low-cost transformer DAA. The 73M1903 is pin-compatible with Teridian’s 73M2901CE modem chip, which facilitates the user to transition from the 73M2901 to a soft modem solution with minimal risk and redesign of the line-side DAA circuitry.
Applications
- Embedded Modem Applications such as Medical and Industrial Telemetry
- Multifunctional Printers (MFPs)
- Personal Video Recorders
- POS Terminals
- Satellite Set-Top Boxes
- Stand-Alone Fax Machines
- Utility Met
