Product Summary

The SYN500R is a general purpose, 3V-5.5V ASK Receiver that operates at 300-450MHz with typical sensitivity of -109dBm. The SYN500R functions as a super-heterodyne receiver for OOK and ASK modulation up to 10kbps. The down-conversion mixer also provides image rejection. All post-detection data filtering is provided on the SYN500R. Any one-of-four filter bandwidths may be selected externally by the user in binary steps, from 1.25KHz to 10KHz. The user need only configure the device with a set of easily determined values, based upon data rate, code modulation format, and desired duty-cycle operation. The applications of the SYN500R include Automotive Remote Keyless Entry (RKE), Remote controls, Remote fan and light control, Garage door and gate openers.
