                            Altera PLL Clock Settings Information
The following table lists the clock settings Information. You can either merge the similar frequency counters in their design, or the Fitter performs the merging automatically.
| Clock | Description | 
|---|---|
| outclk_0 | 600 MHz, used as 2x frequency if necessary. | 
| outclk_1 | 300 MHz, used as strobe/dqs clock. | 
| outclk_2 | 300 MHz, 270 degrees phase shifted. Used as data/dq clock. | 
| outclk_3 | 150 MHz, used as half-rate clock. | 
| outclk_4 | 300 MHz, used to drive the ALTDLL IP core. The minimum frequency for the ALTDLL IP core for Stratix V devices is 300 MHz. | 
| outclk_5 | 300 MHz, used to drive the full rate core clock. | 
| outclk_6 | 150 MHz, used to drive the half rate core clock. | 
| outclk_7 | 25 MHz, used as config_clk. | 
   Note: lf the memory frequency is less than the ALTDLL IP core minimum frequency, then drive the ALTDLL IP core at 2x or 4x of the memory frequency. The DQS phase settings decrease as well.
