Notes to
(1) For enhanced PLLs, m, n range from 1 to 256 and post-scale counters range from 1 to 512 with 50% duty cycle.
(2) For fast PLLs, m, and post-scale counters range from 1 to 32. The n counter ranges from 1 to 4.
(3) The smallest phase shift is determined by the voltage controlled oscillator (V
(4) For degree increments, Arria GX devices can shift all output frequencies in increments of at least 45. Smaller degree increments are possible
(5) Arria GX fast PLLs only support manual clock switchover.
(6) Fast PLLs can drive to any I/O pin as an external clock. For high-speed differential I/O pins, the device uses a data channel to generate
