Hittite HMC914LP4EChelmsford, MA, 09/09/2010 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets has expanded its Limiting Amplifier product line with the release of the HMC914LP4E, a Limiting Amplifier with Loss-of-Signal detection capability. The HMC914LP4E supports data rates up to 12.5 Gbps, and is ideal for SONET/SDH-based transmission systems, OC-192 Fiber Optic modules, 10 Gibabit Ethernet (GbE), 8x & 10x Fiber Channel, or for use as a wideband RF gain block.

The HMC914LP4E Limiting Amplifier is designed to support data transmission rates up to 12.5 Gbps, operates from a single +3.3 V DC supply, and provides 32 dB of differential small signal gain. The amplifier can operate over a wide range of input voltage levels and provides a constant-level differential output swing which may be adjusted up to 750 mVp-p. The outputs of the HMC914LP4E may be operated either singled-ended or differentially. All single-ended input signals are terminated with 50 Ohms to +3.3 V on-chip, and may be either AC or DC coupled.

The HMC914LP4E features a loss-of-signal (LOS) indicator output and a control pin for adjustment of the input signal amplitude threshold level. The HMC914LP4E also features an output level control pin, which allows for loss compensation or for output signal level optimization. The amplifier also provides an analog RSSI (Received Signal Strength Indicator) output voltage which is proportional to input signal amplitude. Integrated DC offset compensation is also provided on chip.

The HMC914LP4E complements many of Hittite’s previously released Fiber Optic and High Speed Logic products, is housed in a plastic RoHS compliant 4 x 4 mm SMT package, and is specified for operation from -40 °C to +85 °C. Released data sheets may be found at www.hittite.com. Samples and evaluation PC boards are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
