The ADF7010 is a low power OOK/ASK/FSK/GFSK UHF transmitter designed for use in ISM band systems. It contains an integrated VCO and sigma-delta fractional-N PLL. The output power, channel spacing, and output frequency are programmable with four 24-bit registers. The fractional-N PLL enables the user to select any channel frequency within the U.S. 902 MHz 928 MHz band, allowing the use of the ADF7010 in frequency hopping systems. It is possible to choose from the four different modulation schemes: Binary or Gaussian Frequency Shift Keying (FSK/GFSK), Amplitude Shift Keying (ASK), or On/Off Keying (OOK). The device also features a crystal compensation register that can provide _1 ppm resolution in the output frequency. Indirect temperature compensation of the crystal can be accomplished inexpensively using this register. Control of the four on-chip registers is via a simple 3-wire interface. The devices operate with a power supply ranging from 2.3 V to 3.6 V and can be powered down when not in use.
