Ultra-Fast ECL-Output Comparator
_______________General DescriptionThe MAX9690 is an ultra-fast ECL comparator manufac-
tured with a high-frequency bipolar process (fT= 6GHz)
capable of very short propagation delays. This design
maintains the excellent DC matching characteristics nor-
mally found only in slower comparators. The MAX9690 is
similar in function to the MAX9685, except the latch-
enable input is eliminated.
The MAX9690 is pin-compatible with the CMP-08 but
exceeds the AC characteristics of that device.
The MAX9690 has differential inputs and complemen-
tary outputs that are fully compatible with ECL-logic lev-
els. Output current levels are capable of driving 50Ω
terminated transmission lines. The ultra-fast operation
makes signal processing possible at frequencies in
excess of 600MHz.

__________Applications Information
LayoutBecause 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 50Wto 120W. 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 Slew-Rate RequirementsAs 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 increase the minimum slew-rate requirement.
____________________Timing DiagramThe 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)
switches the comparator. Outputs –Q–and Q are similar
in timing.
