Notes: 1. Regardless of whether PLL or RTC is used, connect PLLV_CC, RTCV_CC to V_CC, and
PLLGND, RTCGND to GND.
2. With VIH min = V_CC – 0.5 V, VIL max = 0.5 V, and all output pins unloaded.

16.3 AC Characteristics
Input for the SH7708 Series should, as a rule, be clock synchronous. Keep to the setup and
hold times for each input signal unless otherwise directed.
