Product Description
Description:
The CY73 is a ASK/OOK compatible super heterodyne wireless receiving module with high performance for ISM frequency band. High receiving sensitivity and strong ability of resisting. From wireless signal input to data output can be done without any electrical circuit. User only use extra simple data decode circuit can achieve wireless products development.
Features:
Application
Pin Description
Pin-out as showed in figure 1 above
Note 1: ANT pin is a 50 ohm antenna input. The length is about:
23cm for 315MHz
17cm for 433.92MHz
Electrical Characteristics:
Condition: Ta=25ºC Vcc=5.0V Frequency=315MHz
Condition: Ta=25ºC Vcc=5.0V Frequency=433.92MHz
Mechanical Size: (Unit: MM)
Cautions:
The drive current of the data output pin is relatively weak. If the MCU is directly driven, the I/O port must not be connected to the pull-up or pull-down resistor, and the inside pull-up or pull-down resistor must be set in the disabled state.
