Setting Conditions for Measuring Electrical Characteristics
Use the Electrical Characteristics Measurement Circuit on page 22 when measuring electrical characteristics.
For measurement, the digital block must be initialized and power saving must be canceled by performing
Settings 1 and 2 below. In addition, the serial data must be set to the initial settings shown in the table below.
Setting 1. Horizontal AFC adjustment
Input a signal and adjust the VCO using V22 so that WL and WH of the TP24 output waveform are the same.
Setting 2. Canceling power saving mode
The power-on default is power saving mode, so clear (set all "0") serial data PS0, PS1, PS2, PS4 and SYNC GEN.
