1. T_amb = 25 °C, V_{DD_CEC} = 3.3 V, V_{DD_CEC_IC} = 1.8 V, unless otherwise specified
2. Test conditions are compliant with worst case CEC specification:
- Correspond to two 27 kΩ +5% pull-up resistances in parallel (compliant with HDMI CTS)
- Max capacitance corresponding to 9 equipment chained on the CEC bus
3. Maximum capacitance allowed at connector output is 200 pF in HDMI 1.4 specification
