MAX41463/MAX41464 300MHz960MHz (G)FSK 2 Transmitter with I C Interface General Description Benefits and Features The MAX41463/MAX41464 is a UHF sub-GHz ISM/SRD Low Implementation Cost transmitter designed to transmit Frequency-Shift Keying Bits-to-RF Single Wire Operation (FSK), or Gaussian (G)FSK (or 2GFSK) data in the 286MHz Low Bill-of-Materials (BOM) Uses Single, Low-Cost, 16MHz Crystal to 960MHz frequency range. It integrates a fractional phase- locked-loop (PLL) so that a single, low-cost crystal can be Small 3mm x 3mm MAX-10 Package Increased Range, Data Rates, and Security used to generate commonly used world-wide sub-GHz frequencies. The fast response time of the PLL allows for Up to +16dBm PA Output Power Fast Frequency Switching for FHSS/DSSS frequency-hopping spread spectrum protocols for increased range and security. The chip also features preset modes Fast-On Oscillator: <250s Startup Time Up to 200kbps NRZ Data Rate with pin-selectable frequencies so that only one wire is Extend Battery Life with Low Supply Current required for an external microcontroller interface. The only < 12mA Typical Current Consumption at 315MHz frequency-dependent components required are for the Selectable Standby and Shutdown Modes external antenna-matching network. A buffered clock-out Auto Shutdown at < 20nA (typ) Current signal at 800kHz is also provided. Optionally, the device Ease-of-Use can be put into programmable mode and programmed 2 Pin-Selectable Frequencies using an I C interface. The crystal-based architecture Pin-Compatible ASK and FSK Versions of the MAX41463/MAX41464 eliminates many of the +1.8V to +3.6V Single-Supply Operation common problems with SAW-based transmitters by 2 Fully Programmable with 400kHz/1MHz I C providing greater modulation depth, faster frequency Interface settling, higher tolerance of the transmit frequency, and reduced temperature dependence. Ordering Information appears at end of data sheet. The MAX41463/MAX41464 provides output power up to +13dBm into a 50 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 2 programmable register settings in I C mode. Simplified Block Diagram The MAX41463/MAX41464 also features single-supply operation from +1.8V to +3.6V. The device has an auto- shutdown feature to extend battery life and a fast oscillator DATA /SDA PA CONTROL VDD wake-up with data activity detection. GND The MAX41463/MAX41464 is available in a 10-pin DATA ACTIVITY MAX package and is specified over the -40C to +105C DETECTOR extended temperature range.
