Notes
1. Digital clocks are silent and analog bias current is zero.
2. The HUE and SAT DACs are based on a R2R ladder network as describe in the section “HUE and SAT DACs”. The
3. The input configuration of the ADCs is depicted in Fig.20. The minimum difference AV
4. The internal system frequencies are 1728 times the input frequency. For more detailed information about the clock
