VCOs with Differential Output
AC ELECTRICAL CHARACTERISTICS (continued)
(MAX2605–MAX2609 EV kits, V CC = +2.7V to +5.5V, V TUNE = 0.4V to 2.4V, T A = -40°C to +85°C, unless otherwise noted. Typical val-
ues are at V CC = +2.75V, V TUNE = 1.5V, and T A = +25°C.) (Note 1)

Note 1: Production tested at T A = +25°C. Maximum and minimum over temperature limits are guaranteed by design and
characterization.
Note 2: Supply current is measured while the part is oscillating and inductor Q ≥ Q MIN . For MAX2605/MAX2606/MAX2607, Q MIN = 35;
for MAX2608/MAX2609, Q MIN = 40.
Note 3: The DC output current is the total available output signal current.
Note 4: Application range of the part is achieved using external inductance as specified in Figures 1-5 and shown in Figure 6. The inter-
nal varactors support center frequencies of 45MHz to 650MHz. The center frequency is defined by the value of the external
inductor element, L F . The application frequency limits are guaranteed by design and characterization.
Note 5: The guaranteed (tested) limits ? MIN and ? MAX are measured at V TUNE = 0.4V and V TUNE = 2.4V, respectively. Passing
requirements are: ? ≤ ? MIN at V TUNE = 0.4 and ? ≥ ? MAX at V TUNE = 2.4V. The nominal frequency of oscillation is defined by
the inductor.
Note 6: Describes peak tuning gain, which occurs at V TUNE = 0.4V.
Note 7: Measurement at OUT+ or OUT- matched for optimum power transfer into 50 ? load near the center of the operating frequency
range.
Note 8: The phase-noise specifications listed apply to the typical operating circuit shown in Figure 6. Apply over the entire operating
frequency range of the MAX2605–MAX2609.
Note 9: Supply pushing is measured with V CC stepped from +2.7V to +3.2V.
