Description
The MAX2622/MAX2623/MAX2624 self-contained voltage-controlled oscillators (VCOs) combine an integrated oscillator and output buffer in a miniature 8-pin µMAX® package.

The inductor and varactor elements of the tank circuits are integrated on-chip, greatly simplifying application of the part. In addition, the center frequency of oscillation and frequency span are factory preset to provide a guaranteed frequency range versus control voltage. An external tuning voltage controls the oscillation frequency. The output signals are buffered by an amplifier stage (easily matched to 50Ω), using only capacitors to provide higher output power and isolate the devices from load impedance variations.

The MAX2622/MAX2623/MAX2624 operate from a +2.7V to +3.3V supply voltage and require only 9mA of supply current. In shutdown mode, the supply current is reduced to 0.1µA.

An evaluation kit is available:  MAX2622EVKIT, MAX2623EVKIT, MAX2624EVKIT
