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 TBD (design target: 180 MHz or greater). 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.

NOTE

The specification classifications in the “Symbol” column of the tables are

preliminary and may change in future releases of this document.
