This pin is used to select HSTL or 2.5V LVTTL inputs for the FIFO. If HSTL inputs are required, this input must
be tied HIGH. Otherwise it should be tied LOW.
These are Vcc supply inputs and must be connected to the 2.5V supply rail.
These are Ground pins an dmust be connected to the GND rail.
This is a Voltage Reference input and must be connected to a voltage level determined from the table,
“Recommended DC Operating Conditions”. This provides the reference voltage when using HSTL class
inputs. If HSTL class inputs are not being used, this pin should be tied LOW.
This pin should be tied to the desired voltage rail for providing power to the output drivers.
