16 Lead 3x3 mm SMT Package: 9 mm 2 Functional Diagram 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 voltage swing. Overdrive and slew rate dispersion are
typically 10 ps, making the device ideal for a wide
range of applications from ATE to broadband communications. 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. Electrical Specifications TA = +25 ºC, Vcci= +3.3 V, Vcco = +2.0 V, CLK / CLK = 1.6 V to 2.4 V, Vee = -3 V, Vtt = 0 V
