5.5 Clock Timings
T_A = -40^ï¿®C to +85^ï¿®C, V_CC = 5V + 10%
All timings are measured at 1.5V and 50 pF loading on CLKOUT unless otherwise noted.
All output test conditions are with C_L = 50 pF.
For AC tests, input V_IL = 0.45V and V_IH = 2.4V except at X1 where V_IH = V_CC – 0.5V.

NOTES:
1. External clock applied to X1 and X2 not connected.
2. T_CLCK and T_CHCK (CLKIN Low and High times) should not have a duration less than 40% of T_CKIN.
3. Tested under worst case conditions: V_CC = 5.5V. T_A = 70^ï¿®C.
4. Tested under worst case conditions: V_CC = 4.5V. T_A = 0^ï¿®C.
