It integrates a fractional phase- Small 3mm x 3mm MAX-10 Package locked-loop (PLL), so a single, low-cost crystal can be used to generate commonly used world-wide sub-GHz Increased Range, Data Rates, and Security frequencies. The fast response time of the PLL allows Up to +16dBm PA Output Power for frequency-hopping spread spectrum protocols for in- Fast Frequency Switching for FHSS/DSSS creased range and security. The chip also features pre- Fast-On Oscillator: < 250s Startup Time set modes with pin-selectable frequencies so that only Up to 200kbps NRZ Data Rate one wire is required for external microcontroller interface. Extend Battery Life with Low Supply Current The only frequency-dependent components required are < 8mA ASK Manchester Coded for the external antenna matching network. Optionally, Selectable Standby and Shutdown Modes the device can be put into programmable mode and Auto Shutdown at < 20nA (typ) Current 2 programmed using an I C interface. The crystal-based Ease of Use architecture of the MAX41461/MAX41462 elimi- Pin Selectable 300MHz928MHz Frequencies nates many of the common problems with SAW- Pin Compatible ASK and FSK Versions based transmitters by providing greater modulation +1.8V to +3.6V Single-Supply Operation depth, faster frequency settling, higher tolerance of the Fully Programmable with 400kHz/1MHz transmit frequency, and reduced temperature depen- 2 dence. A clock-out signal at 800kHz is also provided. I C Interface The MAX41461/MAX41462 provides output power up to Ordering Information appears at end of data sheet. +13dBm into a 50 load while drawing < 8mA (Manches- Simplified Block Diagram ter coded). The output load can be adjusted to increase power up to +16dBm, and a PA boost mode can be en- DATA abled at frequencies above 850MHz to compensate for /SDA PA VDD CONTROL losses. The PA output power can also be controlled us- 2 GND ing programmable register settings in I C mode. DATA ACTIVITY The MAX41461/MAX41462 also features single-supply DETECTOR operation from +1.8V to +3.6V. The device has an auto- PAOUT PA shutdown feature to extend battery life and a fast oscillator PAGND wake-up with data activity detection. LOCK DETECT FRAC-N PLL The MAX41461/MAX41462 is available in a 10-pin SEL 1:0 MAX package and is specified over the -40C to +105C XTAL1 CRYSTAL CLKOUT /16 extended temperature range. The MAX41461/MAX41462 OSCILLATOR /SCL XTAL2 has an ESD rating of 2.5kV HBM.
