1. DESCRIPTION:
CY49 is a super heterodyne wireless receiving module, which adopts the highly integrated RF wireless data transmission receiving chip. The CY49 is a high performance module at a competitive pricing and small in size. This module improves the stability and reliability of low-end wireless products, improves the image of the product quality and enhances the product competitiveness. It makes some low-end products can get rid of using super-regenerative module due to the limitation of price reason. It can achieve data signal input to wireless signal output without any additional circuits. Users only need to add a simple data decoding circuit and it can easily achieve the development of wireless products.
2. FEATURES:
Frequency: 315M/433.92MHz (custom frequency is available)
Supply voltage: 3.6~5.5v
Receiving sensitivity to -110dBm
Low power consumption, 5.0V @ 433.92MHz, 6.1mA;5.0V @315MHz,4.8mA;continuously data rate transmission to 1.2k (Manchester code)
Good selectivity and stray radiation inhibition ability, image rejection can reach 20dB;
Good capable of suppressing the vibration radiation. Multiple receiving modules can work at the same time (that is single transmitter and multiply receivers). There is no interference with each other it does not affect the receiving distance when multiple receivers work together.
Operating temperature: -30ºC~+80ºC. It can work normally under hostile environment.
Dimension: 12.00×10.50×5.00(mm)
3. APPLICATION:
Remote gate controls, Brake
Remote keyless entry (RKE)
Wireless control Curtain device
Wireless security systems
Wireless Industrial Control
Wireless parking lot barrier
