3,475-MHz PLL/Synthesizer Saves Board Space

Operating at 3,475 MHz with a typical step size of 2,500 kHz, the CPLL66-3475-3475 PLL/synthesizer promises to save space with its compact 0.6” x 0.6” x 0.15” SMD package. It essentially wraps a VCO around a PLL in a package that’s a bit larger than a VCO on its own and significantly smaller than separate VCO/PLL modules. The component requires just an external frequency reference and supply voltages for the internal PLL and VCO and is programmable using a standard three-line interface: data, clock, and load enable. Specs include a typical phase noise of -95 dBc/Hz at a 10 kHz offset and a minimum output power of 3 dBm, a VCO voltage of 5 Vdc, PLL voltage of 3 Vdc, and a second harmonic suppression of -15 dBc typical.
