Refer to the EPD Timing Controller S1C17F13 Manual (separately attached sheet).
R/F Converter (RFC) Characteristics
22.14
R/F converter characteristics change depending on conditions (board pattern, components used, etc.). Use these
characteristic values as a reference and perform evaluation using the actual printed circuit board.
