Key Differentiators
- Ultra-low jitter of 40 fs RMS (vs AD9528BCPZ)
- Three DPLLs with programmable loop bandwidth (vs LMK04828BISQ/NOPB)
- Integrated BAW APLL (vs AD9528BCPZ)
Design Notes
The LMK5C33216RGCR requires a clean 3.3V supply. Use low-ESR ceramic capacitors (e.g., 0.1uF and 10uF) placed close to each VDD pin to minimize power supply noise. A ferrite bead in series with the supply can further isolate high-frequency noise from the clock outputs.
The exposed thermal pad on the VQFN package must be soldered to a ground plane for proper heat dissipation. Use multiple vias under the pad to connect to inner ground layers. Ensure the ground plane is continuous and has low impedance to avoid ground bounce.
Route clock output traces with controlled impedance (e.g., 50 ohms) and keep them as short as possible to minimize reflections and crosstalk. Avoid routing clock traces near noisy digital signals. Use ground vias around clock traces to provide shielding.
