Pin Description Dual-purpose LVDS clock input to PLL1. If differential input to PLL1 is not required, this pin is available as the CLK0 input pin. Dual-purpose LVDS clock input to PLL1. If differential input to PLL1 is not required, this pin is available as the CLK1 input pin. Dual-purpose LVDS clock input to PLL2. If differential input to PLL2 is not required, this pin is available as the CLK2 input pin. Dual-purpose LVDS clock input to PLL2. If differential input to PLL2 is not required, this pin is available as the CLK3 input pin. Optional data strobe signal for use in external memory interfacing. These pins also function as DPCLK pins; therefore, the DQS signals can connect to the global clock network. A programmable delay chain is used to shift the DQS signals by 90 or 72 degrees. Optional data signal for use in external memory interfacing. Optional data mask output signal for use in external memory interfacing.
