Description
Mux select. Selects INB when high. Internal pull-up.
Time out select. See table above. Internal pull-up.
Supply for input clocks only. Can be higher than VDDC.
Input Clock A.
Input Clock B.
Connect to ground.
Output Enable. Tri-states NO_INB when low. Internal pull-up.
Output Enable Tri-states NO_INA when low. Internal pull-up.
Output enable. Tri-states CLK2 when low. Internal pull-up.
Connect to ground.
Goes high when clock on INB stops.
Goes high when clock on INA stops.
Clock 2 Output. Low skew compared to CLK1.
Clock 1 Output. Low skew compared to CLK2.
Main chip supply. Output clocks amplitude will match this VDD.
Output Enable. Tri-states CLK1 when low. Internal pull-up.
Key: I = Input; O = output; P = power supply connection
