Product Description

Description:
The CY42 is ASK/OOK Super Heterodyne receiver module, which can be used to receive un-decoded data from the range of CY's Transmitter modules. The module is very simple to operate and offer a low current consumption. Data can be transmitted directly into a microprocessor or decoding device. All receivers are compatible, producing CMOS/TTL Output, and only require connections to Power & Antenna.


Features:

1. Frequency: 315M/433.92MHz (custom frequency is available)
2. ASK/OOK Demodulation
3. Stable operating frequency
4. Low current consumption
5. Wide operating voltage: 2.4 ~ 5.5V DC
6. High sensitivity: -110dBm

Application

1. Wireless Security Systems
2. Garage Door Controller
3. Remote Gate Controls
4. Data Communications
5. Sensor Reporting

Note:
Because of the weak current of CY42 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.
