DLL Turn Off. When low this input will turn off the DLL inside the device. The AC timings with the DLL turned off will be
different from those listed in this data sheet. There will be an increased propagation delay from the incidence of C and C
propagation delay of other SRAM devices in this speed grade.
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.
