Key Differentiators
- Low jitter of 0.5 ps RMS (vs LMK00306SQX/NOPB)
- 8 outputs (vs LMK00306SQX/NOPB)
- Fractional dividers (vs LMK00306SQX/NOPB)
Design Notes
Ensure proper decoupling of the VDD pins with 0.1uF and 10uF capacitors placed close to the pins. Use a clean ground plane to minimize noise and improve jitter performance.
Place the loop filter components close to the PLL pins to optimize jitter. Use short traces and avoid routing high-speed signals near the loop filter.
The exposed pad must be soldered to a thermal via array to ensure proper heat dissipation. The thermal resistance is [DATA_NEEDED: theta_JA], so adequate copper area is required for high-power operation.
Compliance Information
RoHS compliant per TI product page. Not AEC-Q100 qualified.
