LMX2572RHAR Frequency Synthesizer IC 6.4GHz 1 40-VFQFN Exposed Pad

LMX2572RHAR Frequency Synthesizer IC 6.4GHz 1 40-VFQFN Exposed Pad

Buck Switching Regulator IC Positive Fixed 5V 1 Output 5.5A 22-VFQFN

The LMX2572 is a low-power, high-performance wideband synthesizer that can generate any frequency from 12.5 MHz to 6.4 GHz without using an internal doubler. The PLL delivers excellent performance while consuming just 75 mA from a single 3.3-V supply.
For applications like digital mobile radio (DMR) and wireless microphones, the LMX2572 supports FSK modulation. Discrete level FSK and pulse-shaping FSK are supported. Direct digital FSK modulation is achievable through programming or pins.
