Lt8920tssk tssop-16 2.4G wireless transceiver chip agent shipment
Lt8920 is a low-cost, highly integrated 2.4GHz wireless transceiver chip, which integrates transmitter, receiver, frequency synthesizer and GFSK modem. The transmitter supports adjustable power, and the receiver adopts digital extended communication mechanism, which can achieve excellent transceiver performance under complex environment and strong interference conditions. The peripheral circuit is simple, which only needs to be matched with MCU and a few peripheral passive devices. The lt8920 transmits GFSK signals with a transmit power of 6dbm. The receiver adopts low if structure, and the receiving sensitivity can reach- 96dBm@62.5Kbps 。 Digital channel energy detection can monitor the channel quality at any time.
The on-chip transmit receive FIFO register can communicate with MCU, store data, and then transmit over the air. It has built-in CRC, FEC, auto ACK and retransmission mechanism, which can greatly simplify the system design and optimize the performance.
Digital baseband supports 4-wire SPI and 2-wire I2C interfaces, as well as reset and pkt_ flag, Fifo_ Flag has three digital interfaces. In order to improve the service life of the battery, the chip reduces the power consumption in all links. The working voltage of the chip can be up to 1.9V. Under the condition of holding the register value, the current is 1uA. The chip is packaged with TSSOP16 and SOP16 and complies with ROHS standard.
Single chip solution including RF front end and digital baseband.
