General Description
The HMC874LC3C is a SiGe monolithic, ultra
fast comparator. The comparator supports
20 Gbps operation while providing 120 ps
clock to data output delay and 60 ps minimum pulse
width with 0.2 ps rms random jitter (RJ). 25 Gbps
operation can be achieved with reduced output vol-
tage swing. Overdrive and slew rate dispersion are
typically 10 ps, making the device ideal for a wide
range of applications from ATE to broadband com-
munications. The output stages are designed to directly
drive 400 mV into 50 ohms terminated to Vtt = (Vcco -
2.0 V). The HMC874LC3C features high-speed latches
with programmable hysteresis, and is configured to
operate as a clocked comparator.

[1] VOD is the input overdrive voltage, for example, (VINP - VINN - VOS) where VOS = input offset voltage.
[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.
