Virtex Electrical Characteristics
Based on preliminary characterization. Further changes are not expected.
All specifications are representative of worst-case supply voltage and junction temperature conditions. The parameters
included are common to popular designs and typical applications. Contact the factory for design considerations requiring
more detailed information.

Notes:
1.
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions
is not implied. Exposure to Absolute Maximum Ratings conditions for extended periods of time may affect device reliability.
Power supplies may turn on in any order.
For protracted periods (e.g., longer than a day), V
IN
should not exceed V
CCO
by more that 3.6V.

Notes:
1.
Correct operation is guaranteed with a minimum V
of 2.25V (Nominal V
10%). Below the minimum value stated above,
all delay parameters increase by 3% for each 50 mV reduction in V
CCINT
below the specified range.
At junction temperatures above those listed as Operating Conditions, all delay parameters increase by 0.35% per
°
C.
Input and output measurement threshold is ~50% of V
CC
.
Initialization occurs from the moment of V
CC
ramp-up to the rising transition of the INIT pin.
The device is operational after the INIT pin has transitioned high.
