v10.0514 COMPARATORS -SMT 10 GHz LATCHED COMPARATOR
WITH RSCML OUTPUT STAGE
Typical Applications Features The HMC675LC3C is ideal for: Equivalent Input Bandwidth: 10 GHz • ATE Applications Propagation Delay: 100 ps • High Speed Instrumentation Overdrive & Slew Rate Dispersion: 10 ps • Digital Receiver Systems Minimum Pulse Width: 60 ps • Pulse Spectroscopy Resistor Programmable Hysteresis • High Speed Trigger Circuits Differential Latch Control • Clock & Data Restoration Power Dissipation: 100 mW
RSPECL and RSECL Versions Available
16 Lead 3x3 mm SMT Package: 9 mm 2 Functional Diagram General Description
The HMC675LC3C is a SiGe monolithic, ultra fast
comparator that features reduced swing (RS) CML
output drivers and latch inputs. The comparator
supports 10 Gbps operation while providing 100 ps
propagation delay and 60 ps minimum pulse width with
0.2 ps rms random jitter (RJ). 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 reduced swing CML output stage
is designed to directly drive 400 mV into 50 ohms
terminated to GND. The HMC675LC3C features high
speed latch and programmable hysteresis and may
be configured to operate in either latch mode, or as a
tracking comparator. Electrical Specifications TA = +25 ºC, Vcci= +3.3 V, Vcco = 0 V, Vee = -3 V, VTERM = 0
