Product Description

Description:

CY38 is an ASK/OOK receiver super-heterodyne module, which is designed specifically for unlicensed remote-control and wireless security receiver operating at 315/433.92MHz under FCC Part 15 regulation or pass ETSI certification. The CY38 is based on a single-conversion, super-heterodyne receiver architecture and incorporates an entire Phase-Locked Loop (PLL) for precise local oscillator generation. It can be used in OOK/ HCS/ PWM modulation signal and demodulate to digital signal.                   
CY38 is a high performance module at a competitive cost and easily to design for your product. The CY38 module can be also a RoHS compliance product.

Features:

1. Frequency: 315M/433.92MHz (custom frequency is available)
2. Low cost ASK/OOK radio superhet receiver
3. High frequency stability (no adjust components) & coherence
4. Very low RF re-radiation at the antenna
5. Operation temperature: -20ºC ~70ºC ( It can custom to  -40~85ºC upon requests)
6. Supply voltage: 3.0~5.5V

Application

1. Smart home system
2. Remote controls
3. Remote fan and light control
4. Garage door and gate openers
5. Alarm and security system
