Notes
1. Digital clocks are silent, POR is V_DD.
2. The V_refT and V_refB are made by a resistor division of the V_DD. They can be calculated with the formulas:

The analogue supply voltages are 5 V.
3. The internal system frequency is 1728 times the H_sync input frequency for both the acquisition and display PLLs.
4. The Y-channel is clamped to the V_refB of the ADCs.
5. The UV-channel is clamped to ¹/₂(V_refT + V_refB + V_LSB).
6. The gain of the SAB9076H is 1 under the condition that the R_L is 220 Ω.
