The LMX25 92 device is a low-noise, wideband RF PLL with integrated VCO that supports a frequency range from 20 MHz to 9.8 GHz. The device supports both fractional-N and integer-N modes, with a 32-bit fractional divider allowing fine frequency selection. Integrated noise of 49 fs for 6-GHz output makes it an ideal low-noise source. Combining best-in-class PLL and integrated VCO noise with integrated LDOs, this device removes the need for multiple discrete devices in high performance systems.

The device accepts input frequencies up to 1.4 GHz, which combined with frequency dividers and programmable low noise multiplier allows flexible frequency planning. The additional programmable low-noise multiplier lets users mitigate the impact of integer boundary spurs. In Fractional-N mode, the device can adjust the output phase by a 32-bit resolution. For applications that need fast frequency changes, the device supports a fast calibration option which takes less than 25 µs.

This performance is achieved by using single 3.3-V supply. It supports 2 flexible differential outputs that can be configured as single-ended outputs as well. Users can choose to program one output from the VCO (or doubler) and the second from the channel divider. When not being used, each output can be muted separately.
