2.4Ghz RF transceiver SiP IC with 6Mbps (package type option)
TM2119 is a high power and high data rate out GFSK transceiver operating in the world wide ISM frequency band at 2400~2483.5 MHz. Burst mode transmission and up to 6Mbps air data rate make them suitable for applications requiring ultra low power consumption. The embedded packet processing engines enable their full operation with a very simple MCU as a radio system. Auto re-transmission and auto acknowledge give reliable link without any MCU interference.
TM2119 operates in TDD(Time Division Duplex) mode, either as a transmitter or as a receiver. The RF channel frequency determines the center of the channel used by TM2119. The frequency is set by the RF_CH register in register bank 0 according to the following formula: F0=2400+RF_CH (MHz). The resolution of the RF channel frequency is 1MHz. A transmitter and a receiver must be programmed with the same RF channel frequency to be able to communicate with each other. The output power of TM2119 is set by the RF_PWR bits in the RF_SETUP register.
Demodulation is done with embedded data slicer and bit recovery logic. The air data rate can be programmed to 6Mbps by RF_DR register. A transmitter and a receiver must be programmed with the same setting. In the following chapters, all registers are in register bank 0 except with explicit claim.
