The HMC674LC3C, HMC675LC3C and the HMC676LC3C are a new family of 9.7 GHz latched comparators which feature reduced swing PECL, CML and ECL output drivers and latch inputs respectively. These comparators support 10 Gbps operation while providing 130 ps propagation delay and 60 ps minimum pulse width with 0.8 ps rms random jitter (RJ). Overdrive and slew rate dispersion are typically 10 ps, making them ideal for a wide range of applications including digital receivers, clock and data restoration circuits, pulse spectroscopy, ATE and high speed instrumentation.

Specified for operation from -40 to +85°C, the HMC674LC3C, HMC675LC3C and the HMC676LC3C may be configured to operate in either latch mode, or as tracking comparators, and are housed in ceramic RoHS compliant 3x3 mm SMT packages.

Samples and evaluation PC boards for these products are available from stock and can be ordered via the company's e-commerce site or via direct purchase order.
