Crystal Drive/Clock Input. A crystal with the proper loading capacitors is connected across X1 and X2.
Instead of a crystal, a clock can be applied at the X1 input.
Signal Ground
Clock Multiplier Select. Tri-level digital input.
0 = 1x
Float = 2x
1 = 4x
Spread-Spectrum Magnitude Select. Tri-level digital input.
0 = ±0.5%
Float = ±1.0%
1 = ±1.5%
Power-Down/Spread-Spectrum Disable. Tri-level digital input.
0 = Power-Down/SSO Three-Stated
Float = Power-Up/Spread Spectrum Disabled
1 = Power-Up/Spread Spectrum Enabled
Spread-Spectrum Clock Multiplier Output. Outputs a 1x, 2x, or 4x spread-spectrum version of the crystal
or clock applied at the X1/X2 pins.
Supply Voltage
Crystal Drive Output. A crystal with the proper loading capacitors is connected across X1 and X2.
If a clock is connected to X1, then X2 should be left open circuit.
