Note : Your request will be directed to Texas Instruments.

The LMX2594 is a wideband phased-locked loop with integrated VCO that operates from 10 MHz to 15 GHz. The device is part of the PLLatinum series from TI with a 32-bit fractional divider that allows fine frequency selection and supports both fractional-N and integer-N modes. A frequency ramp generator can synthesize up to 2 segments of ramp in an automatic ramp generation option or a manual option. The fast calibration algorithm allows changing frequencies faster than 20 µs.

The LMX2594 adds support for generating or repeating SYSREF (compliant to JESD204B standard), making it an ideal low-noise clock source for high-speed data converters. Fine delay adjustment (9 ps resolution) is provided in this configuration to account for delay differences of  board traces. The output drivers deliver an output power as high as 7 dBm at 15 GHz. The device runs from a single 3.3 V supply and has integrated LDOs that eliminate the need for on-board low noise LDOs. It is ideal for 5G, mmwave wireless infrastructure, radar, MIMO, phased array antennas and test and measurement applications. The LMX2582 is available in a 40-pin VQFN package that measures for 6 x 6 mm.
