Electrical characteristics

Introduction

This section contains detailed information on power considerations, DC/AC electrical

characteristics, and AC timing specifications for this device.

This device is designed to operate at 120 MHz. The electrical specifications are preliminary

and are from previous designs, design simulations, or initial evaluation. These specifications

may not be fully tested or guaranteed at this early stage of the product life cycle. Finalized

specifications will be published after complete characterization and device qualifications

have been completed.

The “Symbol” column of the electrical parameter and timings tables contains an additional

column containing “SR”, “CC”, “P”, “C”, “T”, or “D”.



“SR” identifies system requirements—conditions that must be provided to ensure

normal device operation. An example is the input voltage of a voltage regulator.



“CC” identifies controller characteristics—indicating the characteristics and timing of

the signals that the chip provides.



“P”, “C”, “T”, or “D” apply only to controller characteristics—specifications that define

normal device operation. They specify how each characteristic is guaranteed.

–

P: parameter is guaranteed by production testing of each individual device.

–

C: parameter is guaranteed by design characterization. Measurements are taken

from a statistically relevant sample size across process variations.

–

T: parameter is guaranteed by design characterization on a small sample size

from typical devices under typical conditions unless otherwise noted. All values

are shown in the typical (“typ”) column are within this category.

–

D: parameters are derived mainly from simulations.
