LVTTL/LVCMOS frequency select input 0. Internal pullup resistor to V
select table 2 for details.
LVTTL/LVCMOS frequency select input 1. Internal pullup resistor to V
select Table 2 for details.
Positive supply voltage pins are connected to +3.3 V supply voltage.
Crystal or Clock input. Connect to 25 MHz crystal source or single-ended clock.
Crystal input. Connect to a 25 MHz crystal or leave unconnected for clock input.
Output enable tri-states output when connected to GND. Internal pullup resistor to V
Ground 0 V. These pins provide GND return path for the devices.
Output current reference pin. Precision resistor (typ. 475 W) is connected to set the out‐
put current.
