Notes to Table 5–15 :
(1) This application uses registered inputs and outputs.
(2) This application uses registered multiplier input and output stages within the DSP block.
(3) This application uses the same clock source for both A and B ports.
(4) This application uses independent clock sources for A and B ports.
(5) This application uses PLL clock outputs that are globally routed to connect and drive M4K clock ports. Use of
non-PLL clock sources or local routing to drive M4K clock ports may result in lower performance numbers than
shown here. Refer to the Quartus II timing report for actual performance numbers.
(6) These numbers are for commercial devices.
(7) These numbers are for automotive devices.
Internal Timing
Refer to Tables 5–16 through 5–19 for the internal timing parameters.
