Crystek's CPLL66-1600-2200 PLL/Synthesizer operates from 1600 to 2200 MHz with a typical Step Size of 1000 KHz. Engineered and manufactured in the USA, the model CPLL66-1600-2200 is housed in a compact 0.6 x 0.6 x 0.15-in. SMD package, which saves board space. Its construction essentially wraps a VCO around a PLL in a package that’s only marginally larger than a VCO on its own, and significantly smaller than separate VCO/PLL modules. The CPLL66-1600-2200 is a complete PLL/Synthesizer needing only an external frequency reference and supply voltages for the internal PLL (phase lock loop) and VCO (voltage controlled oscillator). It is programmed using a standard three line interface (Data, Clock and Load Enable).
