Miniature modem module promises cost savings

Milpitas, Calif. &#151 The XE2422H, a low-cost full-featured modem module from Xecom, Inc., establishes dial-up communications at rates from 300 to 2,400 bits/second and is intended for use in embedded systems that transmit small amounts of data. Typical venues for the module include point-of-sale terminals, vending machines, set-top boxes, and security systems.

Offered as an alternative to having to design, build, and manufacture a modem, the XE2422H eliminates the range of costs and time associated with these tasks, including purchasing, kitting, and placing components. The XE2422H also includes a transferable FCC Part 68 registration, cutting qualification time. At $8 each in volume, the modem's cost approaches that of the components alone.

The modem conforms to pulse and FSK signaling standards used for security alarms. It includes handset interrupt and connect detect functions, allowing the modem to share a phone line with other equipment. During a normal data transfer, the module draws just 15 mA at 3.3 V, consuming less power than competitive modem modules. Between active periods, the modem's sleep and power-down modes further conserve power. Fully tested before shipment, the modem promises to improve end-product quality.

The XE2422H modem module comes on a compact, surface-mount leadless chip carrier, is available now, and sells for less than $8 each in quantities of 100,000 units.
