VCO - Interferencias y Ruido

The datasheet says this VCO covers 300 to 500 Mhz, in this test setup with one coil it covers 350 to 475 Mhz with the controlling voltage.

By changing the supply voltage fed to a classic 4584 Schmitt trigger type oscillator, the oscillator frequency can be changed over a range of 50:1. A 74HCU04 inverter is used at the output of the 4584 to maintain a constant TTL logic level signal.

The LTC®6951 is a high performance, low noise, Phase Locked Loop (PLL) with a fully integrated VCO. The low noise VCO uses no external components and is internally calibrated to the correct output frequency with no external system support. The clock generation section provides five outputs based on the VCO prescaler signal with individual dividers for each output. Four outputs feature very low noise, low skew CML logic. The fifth output is low noise LVDS. All outputs can be synchronized and set.......

The AD9516-01 provides a multi-output clock distribution function with subpicosecond jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from 2.55 GHz to 2. 95 GHz. Optionally, an external VCO/VCXO of up to 2. 4 GHz can be used.The AD9516-0 emphasizes low jitter and phase noise to maximize data converter performance, and it can benefit other applications.......
