Description
Description:
The CY85 is an ASK/OOK compatible super heterodyne wireless receiving module with high performance for ISM frequency band. With the adoption of European brand RF wireless data transferring/receiver chipsets, the module has advantages at high receiving sensitivity, small size and low cost. It solves the problem on space for the small-sized product. 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.
Features:- Frequency: 315MHz/433.92MHz (custom frequency is available);
- High sensitivity -110dBm;
- Supply voltage: 3.6V - 5.5V;
- Low power consumption: 5V @ 315MHz, 4.8mA; 5V @ 433.92MHz, 6.8mA;
- Data Rate: 2.4Kbps (Manchester Code)
- Operating temperature: -20ºC ~ 70ºC, work normally even in the severe temperature environment;
- Excellent inhibiting ability for local oscillator radiation: multiple receivers receive signals from one transmitter simultaneously without any mutual interference and influence on range;
- Favorable selectivity and inhibiting ability for stray radiation; image rejection is up to 20dBm;
- Dimension: 12*10.5*5mm
Application- Remote door openers
- Remote keyless entry
- Wireless security systems
- Remote control
- Wireless door ring
- Wireless data transmission
