DESCRIPTION
Analog ground.
Digital Ground.
Crystal or clock input to device; nominally 25.0 MHz. Requires external load
capacitors.
Crystal drive output from device. Requires external load capacitors.
Output enable (has internal pull_up.): when OE is low, it tristates the clock
output (FOUT)
+3.3 or +5.0 volt supply. (43)
clock output 125 MHz. (44)
Analog power. (Must equal digital power voltage). (43)
Digital and analog power, +3.3 or +5.0 volt supply. (44)
Clock output 125 MHz.
