SAB9076H
Notes
1. Digital clocks are silent, POR is VDD.
2. The VrefT and VrefB are made by a resistor division of the VDD. They can be calculated with the formulas:
and
The analogue supply voltages are 5 V.
3. The internal system frequency is 1728 times the Hsync input frequency for both the acquisition and display PLLs.
4. The Y-channel is clamped to the VrefB of the ADCs.
5. The UV-channel is clamped to 1/2(VrefT +VrefB +VLSB).
6. The gain of the SAB9076H is 1 under the condition that the RL is 220 .
