Internal Clock 16-Bit-Wide Data-Transfer and Scan
Mode (MAX1168 Only)
Force DSPR high and DSEL low for the SPI/QSPI/
MICROWIRE interface mode. The falling edge of
CS
wakes the analog circuitry and allows SCLK to clock in
data (Figure 13). DOUT changes from high-Z to logic
low after
CS
is brought low. Input data latches on the
rising edge of SCLK. The command/configuration/con-
trol register begins reading DIN on the first SCLK rising
edge and ends on the rising edge of the 8th SCLK
cycle. The MAX1168 selects the proper channel for
conversion on the rising edge of the 3rd SCLK cycle.
The internal oscillator activates 125ns after the rising
edge of the 16th SCLK cycle. Turn off the external clock
while the internal clock is on. Turning off SCLK ensures
lowest noise performance during acquisition.
Acquisition begins on the 2nd rising edge of the inter-
nal clock and ends on the falling edge of the 18th inter-
nal clock cycle. Each bit of the conversion result shifts
into memory as it becomes available. The conversion
result is available (MSB first) at DOUT on the falling
edge of
EOC
