Does the output hold time (tCLQX) of the quad-serial configuration (EPCQ) device meet the data hold time after the falling edge on DCLK (tDH) requirement for active serial (AS) configuration in Cyclone® V device? - Does the output hold time (tCLQX) of the quad-serial configuration (EPCQ) device meet the data hold time after the falling edge on DCLK (tDH) requirement for active serial (AS) configuration in Cyclone® V device? Description Yes. The EPCQ devices datasheet doesn't show the tCLQX specifications. But the characterization data shows the minimum tCLQX of EPCQ device is the same as or larger than the minimum tDH requirement for AS configuration shown in the Cyclone® V device datasheet . Resolution See the above description.
