750LP4E

HMC750LP4 / 750LP4E v03.0111 12.5 Gbps LIMITING AMPLIFIER Typical Applications the HmC750lp4(e) is ideal for: • OC-192 receivers • 10 gbps ethernet receivers • 10 gbps fiber Channel receivers • Broadband test & measurement Features supports Data rates up to 12.5 gbps Differential gain: 44 dB 2mV p-p input sensitivity 3 dB Bandwidth: 11 gHz integrated DC Offset Correction adjustable Differential saturated O/p Voltage swing up to 880 mVp-p single +5V power supply Very low rms Jitter Degradation 6 limiting amplifiers - smt 24 lead plastic 4x4mm smt package: 16mm² Functional Diagram General Description HmC750lp4e is a limiting amplifier designed to support data transmission rates up to 12.5 gbps. the amplifier can operate over a wide range of input voltage levels and provides constant-level differential output swing. HmC750lp4e also features an output level control pin, VC1, which allows for loss compensation or for signal level optimization. Differential output signal swing can be adjustable up to 880 mVp-p. input signals higher than 3mV p-p can be amplified to saturated 880mV p-p differential signal. all single-ended input signals to the HmC750lp4e are terminated with 50 ohms to +5V on-chip, and may be either aC or DC coupled. the outputs of the HmC750lp4e may be operated either differentially or single-ended. Outputs can be connected directly to a 50 ohm terminated system referenced to +5V, while DC blocking capacitors may be used if the terminating system is 50 ohms to a non +5V voltage. the HmC750lp4e operates from a single + 5V DC supply and is available in a plastic roHs compliant 4x4 mm smt package.
