Notes:
Voltages are with respect to ground (Vss) unless otherwise stated.
Supply Voltage and operating temperature are as per Recommended Operating Conditions.
Timing parameters are as per AC Electrical Characteristics - Timing Parameter Measurement Voltage Levels
1: Measured with respect to 3/4 bittime, which for 4.096 Mb/s is 244ns x 3/4 = 183ns from beginning of bit cell
2: Measured with respect to 3/4 bittime, which for 8.192 Mb/s is 122ns x 3/4 = 91.5ns from beginning of bit cell
3: CL= 150pF, RL=1 K Ω load.
4: High Impedance is measured by pulling to the appropriate rail with RL with timing corrected to cancel time to discharge CL.
