Note 1: Characterized performance may change if the SKY73100 is configured differently than the test conditions specified here. This characterization used a 6.5 MHz fixed comparison
frequency for the PLL phase loop filter. The PLL synthesizer is programmable up to a maximum comparison frequency of 26 MHz but with degraded performance.
