Notes
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 ¹/₂V_DDD2 + 100 mV for HIGH and ¹/₂V_DDD2 − 100 mV for LOW.
The reference voltage ¹/₂V_DDD2 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/field frequency.
8. B_{–3 dB} = -2---_π----R-----_L---₍--C-----_e^1--_x--_t---₊-----5-----p---F-----₎ with R_L = 37.5 Ω and C_ext = 20 pF (typical).
