Design Notes
The AD4854BCPZ requires a clean power supply for optimal performance. Use low-noise LDO regulators for the analog and digital supplies, and place decoupling capacitors (e.g., 0.1uF and 10uF) close to the VDD and VIO pins. The integrated supply decoupling capacitors help, but external decoupling is still recommended. Ensure the ground plane is solid and avoid sharing analog and digital ground paths.
For best performance, route analog input traces with minimal length and avoid crossing digital signals. Use differential routing for VIN+ and VIN- pairs to maintain common-mode rejection. Place the reference decoupling capacitor close to the REF pin. The 64-BGA package requires careful PCB layout; use a 4-layer or more board with dedicated power and ground planes.
Do not exceed the absolute maximum ratings for supply voltages and input voltages. Ensure the input common-mode voltage is within the specified range to avoid distortion. The LVDS/CMOS interface selection must be configured correctly; refer to the datasheet for proper pin strapping. Also, note that the AD4854BCPZ may have a different package than the AD4854BBCZ, so verify pin compatibility before substitution.
