Product Summary

The SYN450R is a single chip ASK/OOK (ON-OFF Keyed) RF receiver IC. Same as SYN400R, last generation RF receiver IC of Synoxo, SYN450R is a true "antenna-in to data-out" monolithic device. All RF and IF tuning are accomplished automatically within the IC which eliminates manual tuning and reduces production costs. The result is a highly reliable yet low cost solution. However, SYN450R contributes much higher sensitivity than SYN400R. In 433MHz application, the sensitivity of SYN450R can reach -107dBm, which can greatly increases wireless operation distance. The applications of the SYN450R include Automotive Remote Keyless Entry (RKE), Long Range RF Identification, Remote fan and light control, Garage door and gate openers.
