Layout
Because of the MAX9690’s large gain-bandwidth charac-
teristic, special precautions need to be taken if its high-
speed capabilities are to be used. A PC board with a
ground plane is mandatory. Mount all decoupling capac-
itors as close to the power-supply pins as possible, and
process the ECL outputs in microstrip fashion, consistent
with the load termination of 50
to 120
. For low-imped-
ance applications, microstrip layout at the input may also
be helpful. Pay close attention to the bandwidth of the
decoupling and terminating components. Chip compo-
nents can be used to minimize lead inductance.
Input S lew-Rate Requirements
As with all high speed comparators, the high gain-band-
width product of these devices creates oscillation prob-
lems when the input traverses through the linear region.
For clean switching without oscillation or steps in the out-
put waveform, the input must meet certain minimum slew-
rate requirements. The tendency of the part to oscillate is
a function of the layout and source impedance of the cir-
cuit employed. Both poor layout and larger source imped-
ance will increase the minimum slew-rate requirement.
____________________T iming Diagram
The timing diagram illustrates the series of events that
completes the compare function, under worst-case
conditions. The leading edge of the input signal (illus-
trated as a large-amplitude, small-overdrive pulse)
in timing.

OS
Input Offset Voltage—The voltage required
between the input terminals to obtain 0V differ-
ential at the output.
Input Voltage Pulse Amplitude
Input Voltage Overdrive
Input to Output High Delay—The propagation
delay measured from the time the input signal
crosses the input offset voltage to the 50% point
of an output low-to-high transition.
Input to Output Low Delay—The propagation
delay measured from the time the input signal
crosses the input offset voltage to the 50% point
of an output high-to-low transition.
