Figure 10a. External Clock Mode, 15 Clocks/Conversion Timing
Figure 10b. External Clock Mode, 16 Clocks/Conversion Timing
The fastest the MAX1246/MAX1247 can run with
CS
held
low between conversions is 15 clocks per conversion.
Figure 10a shows the serial-interface timing necessary to
perform a conversion every 15 SCLK cycles in external
clock mode. If
CS
is tied low and SCLK is continuous,
guarantee a start bit by first clocking in 16 zeros.
Most microcontrollers (μCs) require that conversions
occur in multiples of 8 SCLK clocks; 16 clocks per con-
version is typically the fastest that a μC can drive the
MAX1246/MAX1247. Figure 10b shows the serial-
interface timing necessary to perform a conversion every
16 SCLK cycles in external clock mode.
