Cloc k Input
The MAX1161 is driven from a single-ended TTL input
(CLK). The CLK pulse width (t
pwH
) must be kept
between 10ns and 300ns to ensure proper operation of
the internal track/hold amplifier (Figure 1a). When oper-
ating the MAX1161 at sampling rates above 3Msps, it is
recommended that the clock input duty cycle be kept
at 50% to optimize performance (Figure 4). The analog
input signal is latched on the rising edge of CLK.
The clock input must be driven from fast TTL logic (VIH
≤
4.5V, t
RISE
<6ns). In the event the clock is driven from
a high current source, use a 100
resistor (R5) in
series to limit current to approximately 45mA.
Digital Outputs
The format of the output data (D0–D9) is straight binary
(Table 2). The outputs are latched on the rising edge of
CLK with a propagation delay typically at 14ns. There is
a one-clock-cycle latency between CLK and the valid
output data (Figure 1a).
The digital outputs’ rise and fall times are not symmetri-
cal. Typical propagation delay is 14ns for the rise time
and 6ns for the fall time (Figure 5). The nonsymmetrical
rise and fall times create approximately 8ns of invalid
data.
Overrange Output
The overrange output (D10) is an indication that the
analog input signal has exceeded the positive full-scale
input voltage by 1LSB. When this condition occurs, D10
will switch to logic 1. All other data outputs (D0–D9) will
remain at logic 1 as long as D10 remains at logic 1.
This feature makes it possible to include the MAX1161
in higher-resolution systems.
Evaluation Board
The MAX1160 EV kit is available to help designers
demonstrate the MAX1160 or MAX1161’s full perfor-
mance. This board includes a reference circuit, clock-
driver circuit, output data latches, and an on-board
reconstruction of the digital data. A separate data sheet
describing the operation of this board is also available.
