DLL Turn Off. When low this input will turn off the DLL inside the device. The AC timings with the DLL
delay from the incidence of C and C to DQ, or K and K to DQ as configured. The propagation delay is not
a tested parameter, but will be similar to the propagation delay of other SRAM devices in this speed
grade.
No connects inside the package. Can be tied to any voltage level
Reference Voltage input. Static input used to set the reference level for HSTL inputs and Outputs as well
as AC measurement points.
Power supply inputs to the core of the device. Should be connected to a 1.8V power supply.
Ground for the device. Should be connected to ground of the system.
Power supply for the outputs of the device. Should be connected to a 1.5V power supply for HSTL or
scaled to the desired output voltage.
