Description
General part information
LMX2572LP Series
The LMX2572LP is a low-power, high-performance wideband synthesizer that can generate one frequency from 12.5 MHz to 2 GHz without the use of an internal doubler. The PLL delivers excellent performance while consuming just 70 mA from a single 3.3-V supply.
For applications like digital mobile radio (DMR) and wireless microphones, the LMX2572LP supports FSK modulation. Discrete level FSK and pulse-shaping FSK are supported. Direct digital FSK modulation is achievable through programming or pins.
The LMX2572LP allows users to synchronize the output of multiple devices and also enables applications that need deterministic delay between input and output. The LMX2572LP provides an option 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 two segments of ramp in an automatic ramp generation option or a manual option for maximum flexibility. The fast calibration algorithm allows the user to change frequencies faster than 20 µs.
