1. 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.                                                                         
 
 
2. FEATURES:                            
Frequency: 315MHz/433.92MHz(custom frequency is available)
High sensitivity -110dbm@433.92 ;
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. 
 
3. APPLICATION:
TPMS/RKE/PKE
Remote controls 
Car alarm systems 
Garage door and gate openers 
Alarm and security system
Automation systems
