Low-Cost Embedded Modem Module Doesn’t Compromise Features

The CH1724 embedded modem module achieves low cost with its careful design for manufacturing efficiency without compromising features. It targets point-of-sale, process control, access security, telemedicine, and remote data-acquisition applications. The CH1724 is a complete modem that complies with FCC Part 68 Registration without the need for external circuitry. Error correction ensures accurate transactions. A fast-connect algorithm completes short messages quickly, and the line-status monitor prevents interference with voice calls when the modem shares the telephone line. The CH1724’s small size keeps cost down and expands the versatility of the modem. It measures 1.6 inches by 0.8 inches and is 0.22 inches high. In addition, leadless surface-mount attachment maximizes space utilization in the embedded system design. The CH1724 cost less than $15 each for typical production volumes.
