• Manufacturer Part Number: pck2001
• Description: 14.318-150 Mhz I2c 1 18 Clock Buffer
• Manufacturer: NXP Semiconductors

1. Clock period and skew are measured on the rising edge at 1.5 V.
2. T
3. T
4. T
5. Duty cycle should be tested with a 50/50% input.
6. Over MIN (20 pF) to MAX (30 pF) discrete load, process, voltage, and temperature.
7. Input edge rate for these tests must be faster than 1 V/ns.
8. Calculated at minimum edge rate (1.5 ns) to guarantee 45/55% duty cycle at 1.5 V. Pulse width is required to be wider at the faster edge to
9. All typical values are at V
10. Typical is measured with MAX (30 pF) discrete load.
11. Typical is measured with MIN (20 pF) discrete load.
