Description
Description:
The CY46 is a super heterodyne wireless receiving module. This module adopts the RF wireless data transmission receiving chip of French brand, which is a high performance of the receiving module of ISM frequency band. It has higher receiver sensitivity, compact small size, and low price. CY46 makes some low-end products can get rid of the limitation of using super-regenerative because of price reason. This module also improves the stability and reliability of low-end wireless products, improve the image of the product quality and enhance the product competitiveness. Any circuit that can be done without additional wireless signal input to the data signal output. Users only need to plus simple data decoding circuit, can easily achieve the development of wireless products.
Features:- High sensitivity: -110dBm;
- Frequency: 315M/433.92MHz (custom frequency is available)
- Low operation voltage: VCC= 3.6-5.5 V;
- Low Current: 4.8mA. 5V@315MHZ / 6.8mA. [email protected], when the continuous data transmission rate reaches 2.4k, the power consumption can be a minimum as 50nA in power supply mode.
- Operating Temperature:-20ºC ~ +70ºC, can work normally even in the harsh environment temperature.
- Small Size of PCB: 23×7.5×5 MM;
- Good selectivity and stray radiation inhibition ability, it's easy to go through the international standard such as CE/FCC.
- The good radiation suppression ability, can work together with multiple receiving modules without interfering with each other.
Application- Remote gate controls
- Remote keyless entry
- Car alarm systems
- Wireless security systems
- Automation systems
- Remote control systems

Mechanical Size: (Unit: MM)Figure2 CY46 DimensionPRE-CAUTION: The driven current of CY46 data output pin is weak, so if direct the single chip microcomputer, please don't add any pull up or pull down resistors on the MCU' I/O port. The MCU internal pull-up and pull down resistors need to be in disabled state too.
PCB dimension has tolerance of 3%.
