Product Details
Place of Origin: | Guangdong, China | Brand Name: | V-chip | Model Number: | VT-CC1120-433 |
Product Description
General Description
VT-CC1120-433M is based on RF Transceiver CC1120 of TI Chipcon,it’s a small size and ultra low power UHF wireless module. CC1120 is fully integrated single-chip radio transceiver designed for high performance at very low power and low voltage operation in cost effective wireless systems. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 164-192 MHz, 410-480 MHz and 820-960 MHz. The MAX RF output power can be set as high as +15dBm, with data rate as high as 200Kbps. The module integrated many RF functions thus you can use it conveniently and reducing your development time.

Note:
1. The module transmission data rate will affect Transmission distance ,the higher the data rate , the closer the distance, and the lower the receiving sensitivity.
2. The supply voltage to the module will affect TX power, in the operating supply voltage range, the lower the voltage, the lower the TX power.
3. The module central frequency will change as the operating temperature change, use it under suggest temperature, the module can work well.
4. The antenna will strongly affect the communication distance, please select matched antenna and connect it correctly.
5. The module mount will affect the communication distance.

Circuit Interface
Note:
The pin sequence above are not the actual pin sequence refer pin description. SPI, I/O interface should connect with the MCU’s I/O pin in order to archive your functions. The circuit must be take ESD protect to prevent damage module. Good RF performance determines on the module position, ground and antenna fixing. Any question about the module please contact with the FAE engineer.
Configuration Registers
The configuration of CC1120 can be done with software SmartRF Studio7. Complete descriptions of the registers are given in the CC1120 datasheet. We can provide evaluation board and demo code to the customer to develop and evaluate the module’s capability.
Dimension
Antenna
We can provide antenna match to the module. And if there is some special requirements to satisfy, we can coordinate with you to select antenna, match antenna to the module in order to make the product work well.
Some recommend antennas as the table below.
Spring antenna(Standard)
Characteristic: small size, low cost, embedded conveniently.
