HMC865LC3 v01.0614 32 Gbps LIMITING AMPLIFIER Typical Applications Features s upports Data r ates up to 43 g bps. t he HmC865LC3 is ideal for: Low power Dissipation: 300 mW Vcc = +3.3V 100 g bps ethernet Differential s mall s ignal g ain: 30 dB 100 g bps Long Haul High input s ensitivity: 10 mVp-p Differential 40 g bps (D)Qps K r eceivers 3-dB Bandwidth: 26.5 g Hz Broadband g ain Block for t est & measurement Adjustable Output Voltage equipment s wing up to 800 mVp-p Differential 2 16 Lead 3x3mm smt package: 9mm Functional Diagram General Description t he HmC865LC3 is a Limiting Amplifier packaged in a leadless 3x3 mm ceramic surface mount package which supports up to 43 g bps operation. t he 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 g bps operation. HmC865LC3 has an internal DC offset correction circuit which provides differential 10 mVpp input sensitivity. All input/output rf signals of the HmC865LC3 are terminated with 50 Ohms to +3.3V on chip and may be either AC or DC coupled. t he outputs of the device can be operated either differentially or single- ended. 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.
