Internal Clock Mode
Select internal clock mode to release the P from the
burden of running the SAR conversion clock. To select
this mode, bit D7 of the control byte must be set to 1
and bit D6 must be set to 0. The internal clock frequen-
cy is then selected, resulting in a 3.6s conversion time.
When using the internal clock mode, connect the CLK
pin either high or low to prevent the pin from floating.
External Clock Mode
To select the external clock mode, bits D6 and D7 of the
control byte must be set to one. Figure 6 shows the clock
and WR timing relationship for internal (Figure 6a) and
external (Figure 6b) acquisition modes with an external
clock. Proper operation requires a 100kHz to 7.6MHz
clock frequency with 30% to 70% duty cycle. Operating
the MAX1090/MAX1092 with clock frequencies lower
than 100kHz is not recommended, because it causes a
voltage droop across the hold capacitor in the T/H stage,
which results in degraded performance.
