73M2901CE

V.22bis Single-Chip Modem

Sets the Standards for Cost-Sensitive Applications Requiring Specific Low-Speed Embedded Modem Functionality and Performance


Description

The 73M2901CE is a single-chip low-speed modem that supports basic modem functionality. The integrated data pump (supporting modulations up to ITU-T V.22 bis), controller, and analog front-end (AFE) are designed specifically for cost-sensitive embedded applications. The modem reduces external component count and cost by incorporating features like parallel phone detect, line-in-use and ring detection without the need for additional external components. Programmable configuration options make this device highly adaptable to a wide variety of applications including satellite set-top boxes, point-of-sale terminals, automatic teller machines, remote-monitoring devices, metering devices, vending machines, and smart card readers.
