MAX1183
where fIN represents the analog input frequency and
tAJ is the time of the aperture jitter.
Clock jitter is especially critical for undersampling
applications. The clock input should always be consid-
ered as an analog input and routed away from any ana-
log input or other digital signal lines.
The MAX1183 clock input operates with a voltage thresh-
old set to VDD/2. Clock inputs with a duty cycle other
than 50% must meet the specifications for high and low
periods as stated in the Electrical Characteristics.
System Timing Requirements
Figure 3 depicts the relationship between the clock
input, analog input, and data output. The MAX1183
samples at the rising edge of the input clock. Output
data for channels A and B is valid on the next rising
edge of the input clock. The output data has an internal
latency of five clock cycles. Figure 4 also determines
the relationship between the input clock parameters
and the valid output data on channels A and B.
Digital Output Data, Output Data Format
Selection (T/B), Output Enable (
OE)
All digital outputs, D0A–D9A (Channel A) and D0B–D9B
(Channel B) are TTL/CMOS logic-compatible. There is a
five-clock-cycle latency between any particular sample
and its corresponding output data. The output coding
can be chosen to be either straight offset binary or
two’s complement (Table 1) controlled by a single pin
(T/B). Pull T/B low to select offset binary and high to
activate two’s complement output coding. The capaci-
tive load on the digital outputs D0A–D9A and D0B–D9B
should be kept as low as possible (<15pF) to avoid
large digital currents that could feed back into the ana-
log portion of the MAX1183, thereby degrading its
dynamic performance. Using buffers on the digital out-
puts of the ADCs can further isolate the digital outputs
from heavy capacitive loads. To further improve the
dynamic performance of the MAX1183, small-series
resistors (e.g., 100) may be added to the digital out-
put paths close to the MAX1183.
