2.4Ghz RF transceiver SiP IC with 2Mbps (package type option)

The IC is a high power out GFSK transceiver operating in the world wide ISM frequency band at 2400~2483.5 MHz. Burst mode transmission and up to 2Mbps 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.

The IC operates in TDD mode, either as a transmitter or as a receiver. The RF channel frequency determines the center of the channel used by TM2104. 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 the IC 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 1Mbps or 2Mbps 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.
