HDTV Continuously Variable
Anti-Aliasing Filters
TIMING CHARACTERISTICS
(AV
values are at AV
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.
Note 5: A master device must provide a hold time of at least 300ns for the SDA signal (referred to V
Note 6: C
Note 7: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
