Cy43 Ask/Ook Super-Heterodyne 315 433.92 MHz RF Receiver Module

Description:The CY43 is a ASK/OOK compatible super heterodyne wireless receiving module with high performance for ISM frequency band. High receiving sensitivity and strong ability of resisting. 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. CY43 is for commercial level version. Features:Frequency: 315MHz/433.92MHz (custom frequency is available);High sensitivity: -114dBm;Supply voltage: 2.4 to 5.5V;IF band: 230KHz @433.92M;Low power consumption: 4.3mA@315M, 4.6mA@433.92M;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.ApplicationCar remote control door switch (RKE)Wireless industrial remote controlRemote door openerWireless security alarmRemote control curtainDrying racks, garbage disposals and other products with motor interferencePin DescriptionFigure1 CY43 Shape & PinsPin-out as showed in figure 1 abovePin NamePin DefinitionANTAntenna InGNDConnect to negative power supplyGNDConnect to negative power supply  VCCConnect to positive power supply VCCConnect to positive power supply DEOptional output:1,  DATA output(default setting)2,  Battery Saving Mode(Working mode in high level input)(Sleeping mode in low level input) DATAData OutputGNDConnect to negative power supplyNote 1: ANT pin is a 50 ohm antenna input.
