Functional Diagram
General Description
The HMC974LC3C is a SiGe monolithic, ultra fast
window comparator with level latched output driver with
reduced swings. The window comparator is based on
the HMC674LC3C single comparator and incorporates
two such comparators and additional output logic.
Three output ports detect whether an analog input
signal is above, below or between two reference levels
supplied at its input as shown on the timing diagram
herein.
The outputs are single-ended negative logic. Incor-
porating 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 Ohms
terminated to a voltage Vterm = Vcco-2 V.
HMC974LC3C features high speed latches that can
either be enabled to latch the output data, or can be
left in the transparent mode to implement a tracking
window comparator.

[1] Vcco can be set between +3.3V and 0V; Vterm = Vcco-2V
RSPECL levels are obtained with Vcco=+3.3V and Vterm=+1.3V;
RSECL levels are obtained with Vcco=0V and Vterm= -2 V
[2] Equivalent Input Bandwidth is calculated with the following formula: Bweq=0.22/√ (TRCOMP2-TRIN2) where TRIN is the 20%/80% transition
time of a quasi-Gaussian signal applied to the comparator input, and TRCOMP is the effective transition time digitized by the comparator.
