External Clock Mode
Select external clock mode by writing the control byte
with D7 = 0 and D6 = 0. Figure 8 shows CLK and WR
timing relationships in internal and external acquisition
modes, with an external clock. A 100kHz to 2.0MHz
external clock with 45% to 55% duty cycle is required
for proper operation. Operating at clock frequencies
lower than 100kHz will cause a voltage droop across
the hold capacitor, and subsequently degrade perfor-
mance.
