HMC871LC5 v02.0110 MICROWAVE & OPTICAL DRIVERS - SMT 10 EA OPTICAL MODULATOR DRIVER, DC - 20 GHz Typical Applications Features The HMC871LC5 is ideal for: Wide Supply Range from 5V to 8V • SONET OC-192 & SDH-STM-64 Transmission Systems Adjustable Output Amplitude up to 4Vp-p • 10 GbE Transmitters • 10 Gbps VSR Modules Low DC Power Consumption, 0.25W for Vout = 2.5Vp-p at Vdd = 5V • Pre-driver for 40 Gbps DQPSK Modules Cross Point Adjustment • Broadband Gain Block for Test & Measurement Equipment 32 Lead 5x5mm SMT Package: 25mm2 Functional Diagram General Description Low Additive RMS Jitter, <300 fs The HMC871LC5 is a GaAs MMIC PHEMT Distributed Driver Amplifier packaged in a leadless 5x5mm surface mount package. The amplifier operates between DC and 20 GHz and provides 15 dB of gain. The output swing cross point is adjustable and saturated output swing is 4Vp-p. Gain flatness is excellent at ±0.5 dB as well as very low additive RMS jitter of 300 fs for 10 Gbps operation. The HMC871LC5 provides VSR and Gigabit Ethernet designers with scalable power dissipation for varying output drive requirements (<0.25W at Vout = 2.5Vp-p and <0.6W at Vout = 4Vp-p). The HMC871LC5 has a very wide supply (Vdd) operating range from +5V to +8V and the I/Os are internally matched to 50 Ohms.
