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

Product Description

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 certification Good 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.
Application Car remote control door switch (RKE) Wireless industrial remote control Remote door opener Wireless security alarm Remote control curtain Drying racks, garbage disposals and other products with motor interference

Cautions:
The drive current of the data output pin is relatively weak. If the MCU is directly driven, the I/O port must not be connected to the pull-up or pull-down resistor, and the inside pull-up or pull-down resistor must be set in the disabled state.
