New 4240 MHz PLL/Synthesizer from Crystek Corp.

ELECTRONICS:  Crystek’s CPLL58-4240-4240 PLL/Synthesizer operates at 4240 MHz with a typical Step Size of 2500 KHz. Engineered and manufactured in the U.S., the model CPLL58-4240-4240 is housed in a compact 0.582- x 0.8- x 0.15-inch SMD package, which saves board space.

Crystek’s PLL/Synthesizer 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 CPLL58-4240-4240 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). The Crystek CPLL58-4240-4240 is programmed using a standard three line interface (Data, Clock and Load Enable).

Typical phase noise for the CPLL58-4240-4240 is -95 dBc/Hz at 10 KHz offset with minimum output power of 3 dBm. VCO voltage is 5V dc; PLL voltage is 3V dc. Second harmonic suppression is -15 dBc typical.
