Texas Instruments PLMX2572RHAT

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.

The LMX2572 allows users to synchronize the output of multiple devices and also enables applications that need deterministic delay between input and output. An option is provided to adjust the phase with fine granularity to account for delay mismatch on the board or within devices. A frequency ramp generator can synthesize up to 2 segments of ramp in an automatic ramp generation option or a manual option for maximum flexibility. The fast calibration algorithm allows changing frequencies faster than 20 µs. The LMX2572 also supports generating or repeating SYSREF (compliant to JESD204B standard) making it an ideal low-power, low-noise clock source for clocking high-speed data converters. Fine delay adjustment is provided in this configuration to account for delay differences of board traces.

The LMX2572 integrates LDOs from a single 3.3-V supply, thus eliminating the need for onboard low-noise LDOs.
