KEDA-MM UWB-LNOF Frequency Source 40MHz~22GHz Spi Communication

Introduction: The UWB-LNOF is a high-performance wideband synthesizer capable of generating any frequency from 40MHz to 22GHz. The high-performance PLL features a -106dBc/Hz quality factor and a high phase detector frequency, achieving extremely low in-band noise and integrated jitter. The high-speed N divider has no prescaler, significantly reducing the amplitude and number of spurious signals. There is also a programmable input multiplier to mitigate integer boundary spurs.

The UWB-LNOF allows users to synchronize the outputs of multiple devices and supports applications requiring
deterministic latency between input and output. A fast calibration algorithm significantly reduces VCO calibration time, supporting systems requiring fast frequency hopping. The UWB-LNOF can generate or repeat a JESD204B-compliant SYSREF, enabling it to be used as a low-noise clock source for high-speed data converters. The synthesizer can be used with an external VCO and also provides a direct PFD input pin to support offset mixing for low-spurious transmission.
