Design Notes

Ensure proper decoupling of VDD and VDDQ supplies with 0.1uF and 1uF capacitors placed as close as possible to the balls. Use a low-impedance ground plane to minimize noise. The 1.35V supply should be regulated to within +0.100/-0.067V to ensure reliable operation.

Follow the PCB layout guidelines in the SK Hynix datasheet for signal integrity. Route differential clock (CK, CK#) and data strobe (DQS, DQS#) pairs with controlled impedance and matched lengths. Keep trace lengths for DQ and address lines balanced to minimize skew.

The 96-ball TFBGA package has a thermal resistance that requires adequate airflow or a heatsink for high-power applications. Ensure the PCB has thermal vias under the package to dissipate heat. The industrial temperature grade allows operation up to 95°C, but derating may be necessary at high data rates.
