Interface Performance Characteristics
Table 13: Interface Performance
Switching Characteristics
Switching characteristics are specified on a per-speed-
grade basis and can be designated as Advance, Prelimi-
nary, or Production. Each designation is defined as follows:
Advance
These specifications are based on simulations only and are
typically available soon after device design specifications
are frozen. Although speed grades with this designation are
considered relatively stable and conservative, some
under-reporting might still occur.
Preliminary
These specifications are based on complete ES (engineer-
ing sample) silicon characterization. Devices and speed
grades with this designation are intended to give a better
indication of the expected performance of production sili-
con. The probability of under-reporting delays is greatly
reduced as compared to Advance data.
Production
These specifications are released once enough production
silicon of a particular device family member has been char-
acterized to provide full correlation between specifications
and devices over numerous production lots. There is no
under-reporting of delays, and customers receive formal
notification of any subsequent changes. Typically, the slow-
est speed grades transition to Production before faster
speed grades.
