Notes for Serial Clock
Serial clock inputs SCK1 and SCK2 are sensitive to any kind of interfering signals (noise on power supply,
induced voltage, etc.). Spurious signals can cause malfunction of the device. Special care for the serial clock
design should be taken. Careful grounding, decoupling and short wiring of SCK1 and SCK2 are recommended.
Intersection of SCK1 and SCK2 with other serial interface lines or close wiring to lines carrying high frequency
signals or large changing currents should be avoided.
It considers for the serial clock to make a waveform stable especially about the rising and falling.
Example 1. good example
Straight rising form and falling
form
Example 2. no good example
It doesn’t bound. It doesn’t make
noise one above another.
Example 3. no good example
It doesn’t make a stair stepping.
