16 MHz differential clock input or CMOS clock input. Use both signals for differ-
ential clock.
Connect CLK- to VCC to enable the CMOS/TTL clock mode. The external
CMOS/TTL clock should be connected to CLK+.
General Purpose I/O.
Factor Test Modes (active high). For normal operation, connect these inputs to
GND.
2.97V to 3.63V power supply.
