VSSQ Ground
VSSQ ground is the reference for the input/output circuitry driven by VDDQ. VSSQ must be
connected to VSS.
Note: Each device in a system should have VDD and VDDQ decoupled with a 0.1µF ceramic
capacitor close to the pin (high frequency, inherently low inductance capacitors should be as
close as possible to the package).
