PLL Power—VCCP is VCC dedicated for PLL use. The voltage should be well-regulated
and the input should be provided with an extremely low impedance path to the VCC
power rail. There is one VCCP input.
Quiet Core (Low) Power—VCCQL is an isolated power for the internal processing logic.
This input must be tied externally to all other chip power inputs. The user must provide
adequate external decoupling capacitors. There are four VCCQL inputs.
Quiet External (High) Power—VCCQH is a quiet power source for I/O lines. This input
must be tied externally to all other chip power inputs. The user must provide adequate
decoupling capacitors. There are four VCCQH inputs.
Address Bus Power—VCCA is an isolated power for sections of the address bus
I/O drivers. This input must be tied externally to all other chip power inputs. The user
must provide adequate external decoupling capacitors. There are four VCCA inputs.
Data Bus Power—VCCD is an isolated power for sections of the data bus I/O drivers.
This input must be tied externally to all other chip power inputs. The user must provide
adequate external decoupling capacitors. There is one VCCD inputs.
Bus Control Power—VCCC is an isolated power for the bus control I/O drivers. This
input must be tied externally to all other chip power inputs. The user must provide ade-
quate external decoupling capacitors. There is one VCCC inputs.
SHI and ESAI —VCCS is an isolated power for the SHI and ESAI. This input must be
tied externally to all other chip power inputsL. The user must provide adequate external
decoupling capacitors. There are three VCCS inputs.
