EVALUATION KIT AVAILABLE Click here for production status of specific part numbers. MAX41463/MAX41464 General Description The MAX41463/MAX41464 is a UHF sub-GHz ISM/SRD transmitter designed to transmit Frequency-Shift Keying (FSK), or Gaussian (G)FSK (or 2GFSK) data in the 286MHz to 960MHz frequency range. It integrates a fractional phaselocked-loop (PLL) so that a single, low-cost crystal can be used to generate commonly used world-wide sub-GHz frequencies. The fast response time of the PLL allows for frequency-hopping spread spectrum protocols for increased range and security. The chip also features preset modes with pin-selectable frequencies so that only one wire is required for an external microcontroller interface. The only frequency-dependent components required are for the external antenna-matching network. A buffered clock-out signal at 800kHz is also provided. Optionally, the device can be put into programmable mode and programmed using an I2C interface. The crystal-based architecture of the MAX41463/MAX41464 eliminates many of the common problems with SAW-based transmitters by providing greater modulation depth, faster frequency settling, higher tolerance of the transmit frequency, and reduced temperature dependence. The MAX41463/MAX41464 provides output power up to +13dBm into a 50Ω load while drawing < 12mA at 315MHz. The output load can be adjusted to increase power up to +16dBm, and a PA boost mode can be enabled at frequencies above 850MHz to compensate for losses. The PA output power can also be controlled using programmable register settings in I2C mode. The MAX41463/MAX41464 also features single-supply operation from +1.8V to +3.6V. The device has an autoshutdown feature to extend battery life and a fast oscillator wake-up with data activity detection. 300MHz–960MHz (G)FSK Transmitter with I2C Interface Benefits and Features ●● Low Implementation Cost • Bits-to-RF Single Wire Operation • Low Bill-of-Materials (BOM) • Uses Single, Low-Cost, 16MHz Crystal • Small 3mm x 3mm TSSOP10 Package ●● Increased Range, Data Rates, and Security • Up to +16dBm PA Output Power • Fast Frequency Switching for FHSS/DSSS • Fast-On Oscillator: <250μs Startup Time • Up to 200kbps NRZ Data Rate ●● Extend Battery Life with Low Supply Current • < 12mA Typical Current Consumption at 315MHz • Selectable Standby and Shutdown Modes • Auto Shutdown at < 20nA (typ) Current ●● Ease-of-Use • Pin-Selectable Frequencies • Pin-Compatible ASK and FSK Versions • +1.8V to +3.6V Single-Supply Operation • Fully Programmable with 400kHz/1MHz I2C Interface Ordering Information appears at end of data sheet.
