Notes:

1. Fpixel is the inverse of Tpixel. Operating frequency range is given here while the actual video clock frequency

should comply with all video timing standards. Refer to Table 1 for supported video timings and corresponding

pixel frequencies.

2. 12-bit dual-edged clocking is supported up to 74.5MHz of PCLK frequency, which covers 720p/1080i.

3. All setup time and hold time specifications are with respect to the latching edge of PCLK selected by the user

through register programming.
