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
www.DataSheeatn4Ud.cforemquency 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 50Ω.
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.
