Product Description

Description:
The CY39 is a ASK/OOK compatible super heterodyne receiver module. CY39 is a superior performance receiver for ISM band. With the adoption of branded industrial RF wireless data receiver chip, CY39 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. Users only need to decode the data plus a simple circuit and then any wireless products development can be easily achieved.


Features:

1. Frequency: 315MHz/433.92MHz(custom frequency is available)
2. High sensitivity -112dBm
3. Power down mode with very low supply current (50nA typ)  
4. Operation temperature: -20ºC ~70ºC
5. Supply voltage: 3.3V - 5V
6. Low power consumption: 6.8mA 5V@ 433.92MHz/ 4.8mA 5V @ 315MHz
7. Data rate: Max. 10Kbps
8. Support RSSI function
9. Excellent inhibiting ability for local oscillator radiation: multiple receivers receive signals from one transmitter simultaneously without any mutual interference and influence on range;
10. Good selectivity and stray radiation suppression ability. Easy to pass CE/FCC certificates.

Application

1. TPMS/RKE/PKE
2. Wireless Industrial remote controls 
3. Remote control curtain
4. Garage door and gate openers 
5. Alarm and security system
6. Wireless data transmission

Note:
Because of the weak current of CY39 data output pin, I/O port on the single chip cannot connect pull-up or pull-down resistor and these resistors inside single chip must be set as disable state if it is needed to directly drive the single chip.
