Description

PLL Power—VCCP is VCC dedicated for Phase Lock Loop (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. VCCP should be bypassed to GNDP

by a 0.1 µF capacitor located as close as possible to the chip package.

Quiet Power—VCCQ 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.

A Power—VCCA is an isolated power for sections of the internal chip logic. This

input must be tied externally to all other chip power inputs. The user must

provide adequate external decoupling capacitors.

D Power—VCCD is an isolated power for sections of the internal chip logic. This

input must be tied externally to all other chip power inputs. The user must

provide adequate external decoupling capacitors.

Host Power—VCCH is an isolated power for the HI I/O drivers. This input must

be tied externally to all other chip power inputs. The user must provide adequate

external decoupling capacitors.

Serial Host Power—VCCS is an isolated power for the SHI I/O drivers. This

input must be tied externally to all other chip power inputs. The user must

provide adequate external decoupling capacitors.
