Tamb = 25 °C, VDD_CEC = 3.3 V, VDD_CEC_IC = 1.8 V, unless otherwise specified

Test conditions are compliant with worst case CEC specification:

- Correspond to two 27 k

Ω +5% pull-up resistances in parallel (compliant with HDMI CTS)

- Max capacitance corresponding to 9 equipment chained on the CEC bus

Maximum capacitance allowed at connector output is 200 pF in HDMI 1.4 specification
