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 frequency
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 1. Figure 6a shows the
clock and WR timing relationship for internal and exter-
nal (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 MAX1262/MAX1264 with clock frequencies lower
than 100kHz is not recommended, because it causes a
voltage droop across the hold capacitor in the T/H
stage that results in degraded performance.
