Table 4–18. Stratix GX Enhanced PLL & Fast PLL Features (Part 2 of 2)
The maximum count value is 1024, with a 50% duty cycle setting on the counter. The maximum count value for
any other duty cycle setting is 512.
For fast PLLs, m and post-scale counters range from 1 to 32.
The smallest phase shift is determined by the VCO period divided by 8.
For degree increments, Stratix GX devices can shift all output frequencies in increments of at least 45°. Smaller
degree increments are possible depending on the frequency and divide parameters.
PLLs 7 and 8 have two output ports per PLL. PLLs 1 and 2 have three output ports per PLL.
Every Stratix GX device has two enhanced PLLs (PLLs 5 and 6) with eight single-ended or four differential outputs
each. Two additional enhanced PLLs (PLLs 11 and 12) in EP1SGX40 devices each have one single-ended output.
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 txclkout.
Every Stratix GX device has two enhanced PLLs with one single-ended or differential external feedback input per
PLL.
