DATA SHEET • SKY73121-11 VCO/SYNTHESIZER
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY73121-11 are provided
in Table 9. The recommended operating conditions are specified
in Table 10 and electrical specifications are provided in Table 11.
Spur suppression measurements are provided in Table 12.
Measurement plots for single sideband phase noise and settling
time are shown in Figures 8 and 9, respectively.
Typical performance characteristics of the SKY73121-11 are
illustrated in Figures 10 through 27.
A typical application schematic for the SKY73121-11 is provided
in Figure 28. The PCB layout footprint for the SKY73121-11 is
provided in Figure 29. Figure 30 shows the package dimensions
for the 38-pin MCM and Figure 31 provides the tape and reel
dimensions.
Electrostatic Discharge (ESD) Sensitivity
The SKY73121-11 ESD threshold level is 250 VDC for the RF_OUT
pin and 2000 VDC for all other pins using Human Body Model
(HBM) testing.
To avoid latent or visible ESD damage, always follow proper ESD
handling precautions.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal values. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. All pins
are rated for a Human Body Model (HBM) Class 1A ESD withstand threshold voltage (250 V).
