Figure 11. Typical Connection Diagram (Serial Mode)
Notes:
- “C” depends on the crystal oscillator (Typ. 10-40pF)
- AVSS and DVSS must be connected the same ground plane
- Digital signals, especially clocks, should be kept away from the R pin in order to avoid an effect to the clock
jitter performance.
