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-

lowing guidelines reflect worst-case values across the
recommended operating conditions. All output jitter and
phase specifications are determined through statistical
measurement at the package pins.
