Data pin for SMBus circuitry, 3.3V tolerant.
Clock pin of SMBus circuitry, 5V tolerant.
Active low input to stop differential output clocks.
Asynchronous, active high input to enable spread spectrum functionality.
Select 14.31818 MHz or 25 Mhz input frequency. 1 = 14.31818 MHz, 0 = 25 MHz
0.7V differential Complementary clock output
0.7V differential true clock output
Ground pin.
Power supply, nominal 3.3V
0.7V differential Complementary clock output
0.7V differential true clock output
Frequency select pin.
Frequency select pin.
This pin establishes the reference current for the differential current-mode output
pairs. This pin requires a fixed precision resistor tied to ground in order to establish
the appropriate current. 475 ohms is the standard value.
Ground pin for the PLL core.
3.3V power for the PLL core.
