Hittite Press Release - January 5, 2010
Hittite’s New Comparator Product Line Targets Medical, Industrial & ATE Applications
20 Gbps Speed at 50% Lower Power Consumption vs. Traditional Comparator Solutions!
Chelmsford, MA, 01/05/10 – Hittite Microwave Corporation, the world class supplier of
complete MMIC based solutions for communication & military markets, has introduced its 23rd product line,
Comparators. Six new, high speed comparators deliver up to 20 Gbps speed at 50% lower power consumption compared
with traditional comparator solutions. A unique combination of 10 GHz input bandwidth, low propagation delay
dispersion, low jitter, and high input common-mode range, makes these comparators ideal for medical, industrial,
ATE, military & space, high speed instrumentation and communications applications.
HMC875LC3C and the
HMC876LC3C are monolithic, ultra fast clocked comparators which feature high speed latches with programmable
hysteresis, and reduced swing PECL, CML and ECL output drivers respectively. These clocked comparators achieve 20
Gbps operation at 150 mW power consumption while providing 120 ps clock-to data-output delay. Minimum input
detectable pulse width is typically 60 ps, and random jitter is specified at only 0.2 ps rms. Common mode input
voltage range is specified at ± 1.75V, and typical overdrive and slew rate dispersion are less than 10 ps.
Also released are three new monolithic, 10 GHz comparators which feature level-latched inputs and reduced swing
PECL, CML and ECL output drivers respectively. The
HMC675LC3C and the
HMC676LC3C comparators support 10 GHz input bandwidth while providing 85 ps propagation delay and 60 ps
minimum pulse width with 0.2 ps rms random jitter. With overdrive and slew rate dispersion of 10 ps and power
consumption of less than 140 mW, these comparators are ideal for digital receivers, clock and data restoration
circuits, and pulse spectroscopy. These devices also feature differential latch control and programmable
hysteresis, and they may be configured to operate in either latch mode, or as tracking comparators.
Housed in compact ceramic RoHS compliant 3x3 mm SMT packages and specified for operation from -40°C to +85°C,
HMC876LC3C clocked comparators complement the
HMC676LC3C level-latched comparators, and are pin-compatible with them.
Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via
the company's e-commerce site or via direct purchase order. View released data sheets and Hittite's complete line
