nominal.
20, 21 gnd Ground. 0 V.
2, 7 vt0, vt1 On-Chip Input Termination Node (Analog). Center tap between internal 50 Ohm
termination resistors.
For a DC coupled LVPECL input connect this pin through a resistor to ground; 50 Ohms
for 3.3V LVPECL or 20 Ohms for 2.5V LVPECL.
For a DC coupled LVDS input or for an AC coupled differential input, leave this pin
unconnected.
4, 5 ctrl0, ctrl1 Digital Control for On-Chip Input Termination (Input). Selects differential input mode;
0: DC coupled LVPECL or LVDS modes
1: AC coupled differential modes
These pins are internally pulled down to GND.
10 NC No Connection. Leave unconnected.
31 sel Input Select (Input). Selects the reference input that is buffered;
0: clk0
1: clk1
This pin is internally pulled down to GND.
