AS Configuration Timing

Table 81.  AS Timing Parameters for AS ×1 and AS ×4 Configurations in Intel® Arria® 10 Devices

The minimum and maximum numbers apply only if you choose the internal oscillator as the clock source for initializing the device.

The tCF2CD, tCF2ST0, tCFG, tSTATUS, and tCF2ST1 timing parameters are identical to the timing parameters for passive serial (PS) mode listed in PS Timing Parameters for Intel® Arria® 10 Devices table.

Symbol Parameter Minimum Maximum Unit
tCO DCLK falling edge to AS_DATA0/ASDO output 2 ns
tSU Data setup time before falling edge on DCLK 1 ns
tDH Data hold time after falling edge on DCLK 1.5 ns
tCD2UM CONF_DONE high to user mode 175 830 μs
tCD2CU CONF_DONE high to CLKUSR enabled 4 × maximum DCLK period
tCD2UMC CONF_DONE high to user mode with CLKUSR option on tCD2CU + (600 × CLKUSR period)
