v07.0616 COMPARATORS -SMT 20 Gbps CLOCKED COMPARATOR Typical Applications Features The HMC874LC3C is ideal for: Propagation Delay Clock to Output: 120 ps • ATE Applications Overdrive & Slew Rate Dispersion: 10 ps • High Speed Instrumentation Minimum Pulse Width: 60 ps • Digital Receiver Systems Resistor Programmable Hysteresis • Pulse Spectroscopy Differential Clock Control • High Speed Trigger Circuits Input Bandwidth: 10 GHz • Clock & Data Restoration Power Dissipation: 150 mW
RSCML Version Available
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
