1 / 6 page ![]() General Description The MAX2622/MAX2623/MAX2624 self-contained volt- age-controlled oscillators (VCOs) combine an integrat- ed 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 matched on-chip to 50 Ω. The MAX2622/MAX2623/MAX2624 operate from a +2.7V to +5.5V supply voltage and require only 8mA of supply current. In shutdown mode, the supply current is reduced to 0.1µA.
