CYTR*0 is a 2.4G wireless transceiver module which is compact small size, low power consumption, and suitable for long distance transmission. This module adapts a low cost, high integration of the 2.4Ghz wireless transceiver chip. This chipset is integrated with a transmitter, a receiver, a frequency synthesizer and a GFSK modem. The support power of the transmitter is adjustable. Adopting digital receiver extension communication mechanism, even in the complex environment and under the condition of strong interference, it can still achieve excellent transceiver performance. The Peripheral circuit is very simple. It only required matching with the MCU and a few peripheral passive devices.
The Wireless transceiver chip transmits of GFSK signal. The biggest transmission power can reach 6dBm. It use low intermediate frequency receiver structure, so the receiving sensitivity can reach **7dBm. The digital channel energy detection can monitor channel quality at any time. The chipset has reception FIFO registers and MCU communication data storage, and then transmission in the air by 1Mbps data rate. The chip itself iw with build in CRC, FEC, auto-ack and retransmission mechanism. It can greatly simplify system design and optimize the performance. The digital baseband supports 4 line SPI and 2 lines of I2C interface. In addition, it comes with three digital interfaces Reset, Pkt_flag and Fifo_flag. In order to improve the battery life, this chip is reducing power consumption in every link. This chip can support the lowest operating voltage to 1.9V and under the condition of keeping register values, the minimum current is 1uA.
This module is integrated with RF related functions and components. Users only need to register through the SPI interface with simple configuration and it can achieve communication, which shorten the development cycle of wireless products.
