GENERAL DESCRIPTION
The HMC974LC3C is a silicon germanium (SiGe) monolithic,
ultra fast window comparator that features reduced swing
positive emitter-coupled logic (RSPECL) output drivers that are
level latched. Three output ports detect whether an analog input
signal is above, below, or between two reference levels supplied
at the input (see Figure 2).
The outputs are single-ended negative logic. Incorporating two
proven comparators at the input provides good dc and dynamic
matching and reduces the input capacitance. The reduced swing
output stages are designed to directly drive 400 mV into 50 Ω
terminated to a voltage (VTERM = VCCO − 2 V).
HMC974LC3C features high speed latches that can either be
enabled to latch the output data or left in the track mode to
implement a tracking window comparator.

1 VOD is the input overdrive voltage, for example, VWIN − VRT = VOD or VWIN − VRB = VOD
.
2 Equivalent input bandwidth is calculated with the following formula: BWEQ = 0.22⁄√(TRCOMP2 − TRIN2), where BWEQ is the equivalent bandwidth formula, TRIN is the 20% to
80% transition time of a quasi Gaussian signal applied to the comparator input, and TRCOMP is the effective transition time digitized by the comparator.

THEORY OF OPERATION
The HMC974LC3C is a window comparator where the range of
the window is defined with RT as the top of the voltage window
range and RB as the bottom of the voltage window range. The
comparator has two modes of operation: track mode and latch
mode. While in track mode, the comparator determines three
things:

APPLICATIONS INFORMATION
EVALUATION BOARD
Table 5. Bill of Materials
The HMC974LC3C evaluation printed circuit board (PCB)
must use RF circuit design techniques. Signal lines must have
50 Ω impedance while the package ground leads must connect
directly to the ground plane of the PCB. The exposed metal
package base must connect to VEE. Ensure the top and bottom
ground planes connect together with via holes. The evaluation
PCB shown in Figure 13 is available from Analog Devices, Inc.,
upon request.
