HMC870LC5 v04.1010 Typical Applications Features The HMC870LC5 is ideal for: Wide Supply Range from 3.3V to 7V • 10 Gbps NRZ MZ & Low VΠ Modulator Driver Adjustable Output Amplitude: 2.5 to 8 Vp-p • 10 Gbps RZ Transmission Low Additive RMS Jitter, <300 fs • 40 Gbps DQPSK Low DC Power Consumption 1W for Vout = 8 Vp-p at Vdd = 7V • Broadband Gain Block for Test & Measurement Equipment OPTICAL & MODULATOR DRIVERS - SMT Cross Point Adjustment • Military & Space 32 Lead 5x5mm SMT Package: 25mm² Functional Diagram General Description The HMC870LC5 is a GaAs MMIC pHEMT Distributed Driver Amplifier packaged in a leadless 5x5 mm surface mount package which operates between DC and 20 GHz. The amplifier provides 17 dB of gain, 8Vp-p saturated output swing and features output swing cross point adjustment. Gain flatness is excellent at ±0.5 dB as well as very low additive RMS jitter of 300 fs for 10 Gbps operation. HMC870LC5 provides Metro and Long Haul designers with scalable power dissipation for varying output drive requirements. (<0.4W at Vout = 3.6 Vp-p and <1W at Vout = 8.5 Vp-p) The HMC870LC5 has a very wide supply (Vdd) operating range from +3.3V to +7V, and the RF I/Os are internally matched to 50 Ohms. 8 8-1 MZ OPTICAL MODULATOR DRIVER, DC - 20 GHz Electrical Specifications, TA = +25° C, Vdd = 7V, Vctl = 1V, Idd = 165mA* Parameter Gain Small Signal Bandwidth Conditions Min.
