User supplies one byte of SCLK, then drives CS
high to relieve processor load while the ADC
converts
After SSTRB transitions high, the user supplies
two bytes of SCLK and reads data at DOUT
External Clock Mode (Mode 0)
The MAX1302’s fastest maximum throughput rate is
achieved operating in external clock mode. SCLK con-
trols both the acquisition and conversion of the analog
signal, facilitating precise control over when the analog
signal is captured. The analog input sampling instant is
at the falling edge of the 14th SCLK (Figure 2).
Since SCLK drives the conversion in external clock
mode, the SCLK frequency should remain constant
while the conversion is clocked. The minimum SCLK
frequency prevents droop in the internal sampling
capacitor voltages during conversion.
SSTRB remains low in the external clock mode, and as a
result may be left unconnected if the MAX1302 will
always be used in the external clock mode.
