What the ADF4001BRUZ Does – RF PLL Clock Generator
The ADF4001BRUZ is an RF clock generator built around a phase-locked loop (PLL) core, designed to synthesize clean clock outputs from a CMOS or TTL reference input. It handles input frequencies up to 200 MHz and delivers a differential or single-ended clock output – the PLL locks the output phase to the reference, making it a fit for local-oscillator generation in wireless infrastructure, test equipment, and satellite receivers. A single PLL circuit with a 2:1 input-to-output ratio means one reference feeds one clock output, with an internal divider on the feedback path.
The 16-TSSOP package with 0.65 mm pitch demands a controlled-impedance layout on the reference input trace – route it as a 50-ohm microstrip away from switching noise.
