- **Power-Down Mode:** Reduces current consumption to <1µA when inactive.  
- **Digital Interface:** SPI-compatible for easy configuration.  
- **Applications:** Remote keyless entry (RKE), tire pressure monitoring (TPMS), wireless sensors, and industrial controls.  

This device is designed for reliable, low-power wireless communication in automotive and industrial environments.

Application Scenarios & Design Considerations

High-Performance, 288MHz to 945MHz ASK/FSK ISM Transmitter

Alternative Part Number

  • SI4133-D-GT --: Dual-band RF synthesizer with integrated VCOs, functionally similar to the MAX7049 RF tuner/synthesizer and usable as a drop-in design alternative in many RF front-end applications.
  • LMX2571SQE/NOPB --: Low-power wideband RF synthesizer with integrated VCO covering similar frequency ranges, offering comparable PLL performance for tuner and local oscillator designs.
  • ADF4351BCPZ --: Wideband fractional-N PLL synthesizer with integrated VCO, a well-established alternative for RF signal generation where the MAX7049 is used.
