Hittite Microwave’s latest limiting amplifier, the HMC914LP4E has a loss-of-signal detection capability.

The amplifier is designed to support data transmission rates up to 12.5Gbit/s, operates from a single +3.3 Vdc supply, and provides 32dB 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 750mVp-p. The outputs of the HMC914LP4E may be operated either singled-ended or differentially. All single-ended input signals are terminated with 50ohm to +3.3V on-chip, and may be either AC or DC coupled.

The 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 HMC914LP4E supports data rates up to 12.5Gbit/s, and so is suitable for SONET/SDH-based transmission systems, OC-192 Fiber Optic modules, 10Gibabit Ethernet (GbE), 8x & 10x Fiber Channel, or for use as a wideband RF gain block.
