[1] Minimum value for I2C-bus bit DOWNA = 1.

[2] Minimum value for I2C-bus bit DOWND = 1.

[3] Levels refer to pins PD11 to PD0, FSVGC, PIXCLKI, VSVGC, PIXCLKO, CBO, TVD, and HSVGC, being inputs or outputs directly

connected to a graphics controller. Input sensitivity is 1â2VDD(DVO) + 100 mV for HIGH and 1â2VDD(DVO) â 100 mV for LOW. The reference

voltage 1â2VDD(DVO) is generated on chip.

[4] The data is for both input and output direction.

[5] This parameter is arbitrary, if PIXCLKI is looped through the VGC.

[6] Tested with programming IFBP = 1.

[7] If an internal oscillator is used, crystal deviation of nominal frequency is directly proportional to the deviation of subcarrier frequency and

line/ï¬eld frequency.

[8] Bâ3dB = 2----Ï---(---R----o---(-L---)--(---C---1-e---x--t---+-----5-----p----F----)---) with Ro(L) = 37.5 â¦ and Cext = 20 pF (typical).
