  • OC-192 receivers
  • 10 gbps ethernet receivers
  • 10 gbps fiber Channel receivers
  • Broadband test & measurement 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 s aturated O/p Voltage swing up to 880 mVp-p single +5V power supply Very low rms Jitter Degradation 24 lead plastic 4x4mm smt package: 16mm² HmC750lp4e is a limiting amplifier designed to sup- port 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. H mC750lp4e 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 H mC750lp4e 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 H mC750lp4e operates from a single + 5V DC supply and is available in a plastic roHs compliant 4x4 mm smt package. parameter Conditions min. typ. max.

Application Information

Setting the output swing using external resistor Rc the HmC750lp4e features output swing level adjustment by using VC1 pin. Output swing can be adjusted to the desired level by applying a DC voltage to VC1 pin. Differential output swing vs. control voltage relationship is given in the plot below. Differential Output vs. Control Voltage 200 400 600 800 1000 1200 +25C +85C -40C CONTROL VOLTAGE VC1 (V) DIFFERENTIAL VOLTAGE (mV) in order to adjust the DC voltage on VC1 pin a resistor, rc (r7 in application circuit), should be connected between VC1 pin and VCC as shown in the figure below. the value of the resistor can be chosen using the following equation as a function of VC1. VC1 DC voltage value can be chosen by using the plot given above.
