Oversampling Clock
XCLK internally connects to a clock-frequency divider
network, whose output is the ADC oversampling clock,
fOSC. This allows the selected clock source (internal RC
oscillator or external clock applied to XCLK) to be
divided by one, two, or four (see
Clock Divider-Ratio
Control Bits).
Figure 3 shows the two methods for providing the over-
sampling clock to the MAX110/MAX111. In external-
clock mode (Figure 3a), the internal RC oscillator is
disabled and XCLK accepts a TTL/CMOS-level clock to
provide the oversampling clock to the ADC.
Select external-clock mode (Figure 3a) by connecting
RCSEL to GND and a TTL/CMOS-compatible clock to
XCLK (see
Selecting the Oversampling Clock
Frequency).
In RC-oscillator mode (Figure 3b), the internal RC oscil-
lator is active and its output is connected to XCLK
(Figure 1). Select RC-oscillator mode by connecting
RCSEL to VDD. This enables the internal oscillator and
connects it to XCLK for use by the ADC and external
system components. Minimize the capacitive loading on
XCLK when using the internal RC oscillator.
