Description:
The CY24 is a ASK/OOK compatible super heterodyne receiver module. CY24 is a superior performance receiver for ISM band. With the adoption of Infineon's Industrial RF wireless data receiver chip, CY24 has the high receiving sensitivity and strong anti-interference ability. It can do wireless signal input to the data signal output without any external circuit. Its superior performance makes a lot of before market car manufactures adopt this module as the preferred choice for RKE receiver module. Users only need to decode the data plus a simple circuit and then any wireless products development can be easily achieved.
Features:
- Frequency: 315MHz/433.92MHz(custom frequency is available)
- High sensitivity [email protected] ;
- Power down mode with very low supply current (100nA typ)
- Higher sensitivity: -110dBm
- Operation temperature: -40ºC ~85ºC, it can work even under harsh environment.
- Supply voltage: 5V ±10%
- Low current: 4.6mA(5V, 315MHz)
- If use the power enable mode, the power consumption is as low as 100nA.
- Be compatible with most (ASK/OOK) transmitters
- Fully integrated VCO and PLL Synthesizer
- Good selectivity and stray radiation inhibition ability, easy to go through the international standard certification.
- Good capable of suppressing the vibration radiation. It can work with multiple receiving module (which means one transmitter and multiple receivers) and do not interfere with each other when work at the same time. It does not affect the receiver distance.
Application
- TPMS/RKE/PKE
- Remote controls
- Car alarm systems
- Garage door and gate openers
- Alarm and security system
- Automation systems

Pre-Caution:
The CY24 module data output pin drive current is weak, so if it directly to drive the single chip microcomputer, then the I/O port of MCU can't be connected with to pull -up or pull-down resistors. And please disable the pull-up and pull-down resistors inside the MCU.
