HMC865LC3C v02.0911 32 Gbps LIMITING AMPLIFIER Typical Applications Features The HMC865LC3C is ideal for: Supports Data Rates up to 43 Gbps. •• 100 Gbps Ethernet Low Power Dissipation: 300 mW @ Vcc = +3.3V •• 100 Gbps Long Haul Differential Small Signal Gain: 30 dB •• 40 Gbps (D)QPSK Receivers High Input Sensitivity: 10 mVp-p Differential 3-dB Bandwidth: 26.5 GHz •• Broadband Gain Block for Test & Measurement Equipment Adjustable Output Voltage Swing up to 800 mVp-p Differential 16 Lead 3x3mm SMT package: 9mm2 limiting amplifiers - smt 6 Functional Diagram General Description The HMC865LC3C is a Limiting Amplifier packaged in a leadless 3x3 mm ceramic surface mount package which supports up to 43 Gbps operation. The amplifier provides 30 dB of differential gain. Output voltage swing is adjustable up to 800 mVp-p differential by using the VAC analog control input. Additive rms jitter is less than 300 fs for 32 Gbps operation. HMC865LC3C has an internal DC offset correction circuit which provides differential 10 mVpp input sensitivity. All input/output RF signals of the HMC865LC3C are terminated with 50 Ohms to +3.3V on chip and may be either AC or DC coupled. The outputs of the device can be operated either differentially or singleended. Outputs can be connected directly to 50 Ohm terminated system referenced to 3.3V, while DC blocking capacitors may be used if the terminating system is 50 Ohms to a non 3.3V level.
