... 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. ...

... Ground Connection for Output Buffer. Requires a low-inductance connection to the circuit board 8 GND ground plane. Detailed Description The MAX2622/MAX2623/MAX2624 VCOs are imple- mented oscillator topology, integrating all of the tank components on-chip. This fully monolithic approach provides an extremely easy-to-use VCO, equivalent to a VCO module. The frequency is con- trolled by a voltage applied to the TUNE pin, which is internally connected to the varactor ...
