LMX2572 Overview
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.
