FX919BD5

Overview

The FX919BD5 is a highly integrated data processor from CML Microcircuits, designed for telecom interface applications. It combines a Medium Access Control (MAC) unit with a 4FSK packet data modem. The device supports half-duplex communication with data rates ranging from 4800 to 19.2 kbits/sec. It operates on a supply voltage between 3.3V and 5V. The IC features excellent radio fading performance and includes built-in error detection and correction capabilities. Packaged in a 24-SSOP format, it serves as a complete modulator/demodulator solution for wireless data transmission systems requiring robust signal processing.

Feature Summary

Procurement Notes

Verify the exact suffix against the manufacturer datasheet to confirm package type and tape/reel specifications. Confirm operational voltage ranges match system requirements. Check current availability status as components may have limited stock or end-of-life implications. Ensure environmental compliance documentation aligns with target market regulations before finalizing procurement orders.

Selection Notes

Choose this component when a single-chip solution for MAC and FSK modulation is required. It suits designs needing moderate data rates up to 19.2 kbps. Consider the 24-SSOP package constraints for PCB layout. Evaluate if the integrated error correction meets link budget requirements. Compare against discrete modem solutions for size and power efficiency benefits.
