External Clock Operation
To accommodate designs that use an external clock,
the MAX1003’s internal oscillator can be overdriven by
an external clock source as shown in Figure 7. The
external clock source should be a sinusoid to minimize
clock phase noise and jitter, which can degrade the
ADCs’ ENOB performance. AC couple the clock source
(recommended voltage level is approximately 1Vp-p) to
the oscillator inputs as shown in Figure 7.
Output Data Format
The conversion results are output on a dual, 6-bit-wide
data bus. Data is latched into the ADC output latch fol-
lowing a pipeline delay of one clock cycle, as shown in
Figure 8. Output data is clocked out of the respective
ADC’s data output pins (D_0 through D_5) on the rising
edge of the clock output (DCLK), with a DCLK-to-data
propagation delay (t
PD
) of 3.6ns. The MAX1003 outputs
are +3.3V CMOS-logic compatible.
T ransfer Func tion
Figure 9 shows the MAX1003’s nominal transfer function.
Output coding is offset binary with 1LSB = FSR / 63.
