XQ4028EX DC Characteristics Over Recommended Operating Conditions
Note 1: With up to 64 pins simultaneously sinking 12 mA.
Note 2: With no output current loads, no active input or Longline pull-up resistors, all package pins at Vcc or GND.
XQ4028EX Global Buffer Switching Characteristic Guidelines
Testing of the switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are 100%
functionally tested. Internal timing parameters are derived from measuring internal test patterns. Listed below are
representative values where one global clock input drives one vertical clock line in each accessible column, and where all
accessible IOB and CLB flip-flops are clocked by the global clock net.
When fewer vertical clock lines are connected, the clock distribution is faster; when multiple clock lines per column are
driven from the same global clock, the delay is longer. For more specific, more precise, and worst-case guaranteed data,
reflecting the actual routing structure, use the values provided by the static timing analyzer (TRCE in the Xilinx Development
System) and back-annotated to the simulation netlist. These path delays, provided as a guideline, have been extracted from
the static timing analyzer report. All timing parameters assume worst-case operating conditions (supply voltage and junction
temperature).
