As high-speed receivers, the MAX9691/MAX9692/
MAX9693 are capable of processing signals in excess
of 600MHz. Figure 2 is a 100MHz example with an
input signal level of 14mV
The timing diagram (Figure 3) illustrates the series of
events that complete the compare function, under
worst-case conditions. The top line of the diagram illus-

trates two latch-enable pulses. Each pulse is high for
the compare function and low for the latch function. The
first pulse demonstrates the compare function; part of
the input action takes place during the compare mode.
The second pulse demonstrates a compare function
interval during which there is no change in the input.
The leading edge of the input signal (illustrated as a
large-amplitude, small-overdrive pulse) switches the

The MAX9691/MAX9692/MAX9693 will not false trip
(i.e., output invert) if one of the inputs is in the valid
common-mode range while the other input is outside
the common-mode range.
