1. DESCRIPTION:
CY52 is a super heterodyne wireless receiving module adopts high quality RF wireless data transmission receiving chip. It is a high performance receiving module in ISM frequency band. It has higher receiver sensitivity, compact small in size and low cost which is very suitable for products that with limit space. It can easily achieve the development of wireless products by adding a simple data decoding circuit.
2. FEATURES:
Frequency: 315M/433.92MHz (custom frequency is available)
Supply voltage: 3.6~5.5v
Data Rate: 2.4Kbps.
Receiving sensitivity to -110dBm
Low power consumption, 5.0V @ 433.92MHz, 7.2mA;5.0V @315MHz,5mA;continuously data rate transmission to 2.4k (Manchester code)
Good selectivity and stray radiation inhibition ability, image suppression 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: -20ºC~+70ºC. It can work normally under hostile environment.
Dimension: 17.45×10.80×5.00(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
