Note 1: The filter passband edge is set to code 255.

Note 2: The filter passband edge is set to code 40.

Note 3: 1H is the total line period, depending on the video standard. For NTSC, this is 63.5µs; for HDTV, the line period is 29.64µs.

Note 4: The clamp level is at the sync tip for signals with sync pulses, and at the blanking level otherwise.

the undefined region of SCL’s falling edge.

Note 7: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
