Cy51 Ask/Ook Super-Heterodyne 315 433.92 MHz RF Receiver Module

Description:The CY51 is an ASK/OOK compatible super heterodyne wireless receiving module with high performance for ISM frequency band. With the adoption of high-quality RF wireless data transferring/receiver chipset, the module has advantages at high receiving sensitivity and strong interference performance. From wireless signal input to data output can be done without any electrical circuit. User only use extra simple data decode circuit can achieve wireless products development.Features:Receive sensitivity reaches -114dBm;Working frequency: 315 MHz; 433.92 MHz; (Special frequency can be customized according to customer requirements);Power supply voltage input range: 1.8V-5.5V;Low power consumption, 5.0V @ 315MHz, 4.3mA; 5.0V @ 433.92MHz, 4.6mA Good selectivity and stray radiation suppression ability, easy to pass CE / FCC international certificationGood local oscillation radiation suppression ability, can work with multiple receiving modules (single transmission and multiple reception) without interference with each other, use together without Affect the receiving distance.Temperature range: -20-70 ºC, it can work normally even in harsh ambient temperature.ApplicationCar remote control door switch (RKE)Remote door openerWireless security alarmWireless door bellDrying racks, garbage disposals and other products with motor interferencePin DescriptionPin-out as showed in figure 1 abovePin NamePin DefinitionANTRF signal input pin, connect antenna outside(Note1)GNDConnect to negative power supplyENBattery saving mode(shut down)(Working mode in High level input)(Sleeping mode in Low level input) GNDConnect to negative power supplyDATAData output pin, connect to MCU or decoder's input pin+5VConnect to positive power supplyNote 1: ANT pin is a 50 ohm antenna input.
