Description

Features: Single-chip solution including RF front-end and digital baseband.  Support frequency hopping  Support SPI and I2C interface  Built-in auto_ack function  Data rate 1Mbps, 250Kbps, 125Kbps, 62.5Kbps  At 1Mbps, the synchronization bits are 64bits, 48bits, 32bits, 16bits; 250Kbps, 125Kbps, 62.5Kbps time synchronization bit For 32bits, 16bits. It is recommended to use 32bits, with a fault tolerance of 1bits.  Very low power consumption The LT8920 is a low cost, highly integrated 2.4GHZ Line transceiver chip, on-chip integrated transmitter, receiver, frequency synthesizer, GFSK modem. The transmitter supports adjustable power, and the receiver adopts Digital extended communication mechanism, in complex environment and strong interference conditions, can To achieve excellent transceiver performance. The peripheral circuit is simple, only need to match the MCU and a few peripheral passive devices. LT8920 transmits GFSK signal, sends The maximum transmit power can reach 6dBm. The receiver adopts a low-IF structure, The receiver sensitivity can reach -96dBm@62.5Kbps. digital channel energy Detection can monitor the channel quality at any time. The on-chip transmit and receive FIFO registers can communicate with the MCU message, store the data, and transmit it over the air. It has built-in CRC, FEC, Auto-ack and retransmission mechanisms can greatly simplify system design and optimize performance can. The digital baseband supports 4-wire SPI and 2-wire I2C interfaces, in
