PLL/Synthesizer in SMD Package Saves on Board Space

Thu, 10/08/2009 - 12:09pm


Crystek's CPLL66-2416-2553 PLL/Synthesizer operates from 2416 MHz to 2553 MHz with a typical Step Size of 100 kHz. Engineered and manufactured in the USA, the model CPLL66-2416-2553 is housed in a compact 0.6" x 0.6" x 0.15" SMD package, which saves board space. The company's PLL/Synthesizer construction essentially wraps a VCO around a PLL in a package that is only marginally larger than a VCO on its own, and significantly smaller than separate VCO/PLL modules. The CPLL66-2416-2553 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 device is programmed using a standard three line interface (Data, Clock and Load Enable). Typical phase noise for the CPLL66-2416-2553 is -90 dBc/Hz at 10 kHz offset with minimum output power of 3 dBm. VCO voltage is 5 Vdc; PLL voltage is 3 Vdc. Second harmonic suppression is -15 dBc typical.
