LT8920 2.4GHz SPI Wireless Transceiver RF Chip TSSOP16

LT8920 2.4GHz SPI Wireless Transceiver RF Chip TSSOP16


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 addition to There are Reset, Pkt_flag, Fifo_flag three digital interfaces.

In order to improve the battery life, the chip reduces the power consumption in each link. power consumption, the minimum operating voltage of the chip can reach 1.9V, in the holding register value bar Under conditions, the minimum current is 1uA. The chip is packaged in TSSOP16 and SOP16, RoHS compliant


 Support signal energy detection

 Single-chip transmission distance of 200 meters

 Packages that support SOP16 and TSSOP16
