Product Instruction:
LMX2595 high-performance broadband synthesizer can generate any frequency in the range of 10MHz to 20GHz. The integrated doubler is used to generate frequencies above 15GHz. A high-performance PLL with a quality factor of -236dBc/Hz and a high phase detector frequency can achieve very low in-band noise and integrated jitter. The high-speed N divider has no prescaler, which significantly reduces the amplitude and number of spurs. There is also a programmable input multiplier that reduces spurs on integer boundaries.

LMX2595 allows users to synchronize the output of multiple devices, and can be used in situations where it is determined that a delay is required between input and output. The frequency ramp generator can synthesize up to 2 ramps in the automatic ramp generation option or the manual option to achieve maximum flexibility. The fast calibration algorithm can speed up the frequency to more than 20µs. LMX2595 adds support for generating or repeating SYSREF (compliant with JESD204B standard). This SYSREF is an ideal low-noise clock source for high-speed data converters. In this configuration, a fine delay adjustment (9ps resolution) is provided to solve the delay difference of the board trace.

The output driver in LMX2595 provides up to 7dBm output power when the carrier frequency is 15GHz. The device uses a single 3.3V power supply and has an integrated LDO, eliminating the need for an on-board low-noise LDO.
