Power Inputs

Power Name

Description

VCCN

Normal Power

—VCCN inputs are VCC provided for general use with the

DSP96002 peripheral circuits. This input must be tied externally to all other chip

power inputs. The user must provide adequate external decoupling capacitors.

VCCQ

Quiet Power—

VCCQ inputs provide isolated power for the internal processing

logic. The voltage should be well-regulated, and the input should be provided

with an extremely low impedance path to the VCC power rail. This input must be

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

external decoupling capacitors.

Note:

The number of available power connecctions is package-dependent. See Section 3 for a detailed

description of individual package pinouts.

Grounds

Ground Name

Description

GNDN

Normal Ground

—GNDP connections provide a ground return for the DSP96002

peripheral circuits. This connection must be tied externally to all other chip

ground connections. The user must provide adequate external decoupling

capacitors.

GNDQ

Quiet Ground

—GNDQ is an isolated ground for the internal processing logic.

The connection should be provided with an extremely low-impedance path to

ground. This connection must be tied externally to all other chip ground

connections. The user must provide adequate external decoupling capacitors.

Note:

The number of available ground connecctions is package-dependent. See Section 3 for a detailed

description of individual package pinouts.
