14. Test information

Test data are given in Table 52.

RL = load resistance.

CL = load capacitance includes jig and probe capacitance.

RT = termination resistance should be equal to the output impedance ZO of the pulse generators.

Test data are given in Table 53.

RL = load resistance. RL for SDA and SCL > 1 kΩ (3 mA or less current).

CL = load capacitance includes jig and probe capacitance.

RT = termination resistance should be equal to the output impedance ZO of the pulse generators.
