DCM Timing Parameters
Testing of switching parameters is modeled after testing
methods specified by MIL-M-38510/605; all devices are
100% functionally tested. Because of the difficulty in directly
measuring many internal timing parameters, those parame-
ters are derived from benchmark timing patterns. The fol-

CLK0, CLK90, CLK180, CLK270
CLK2X, CLK2X180

CLKFX, CLKFX180
IFF = Input Flip-Flop or Latch
Setup time is measured relative to the Global Clock input signal with the fastest route and the lightest load. Hold time is measured
relative to the Global Clock input signal with the slowest route and heaviest load.
A Zero “0” Hold Time listing indicates no hold time or a negative hold time. Negative values can not be guaranteed “best-case”, but
if a “0” is listed, there is no positive hold time.
