HMC720LP3E v01.1010 14 Gbps, FAST RISE TIME 1:2 FANOUT BUFFER w/ PROGRAMMABLE OUTPUT VOLTAGE T ypical Applications Features The HMC720LP3E is ideal for: Inputs Terminated Internally in 50 Ohms 16 G Fiber Channel Differential Inputs are DC Coupled RF ATE Applications Propagation Delay: 120 ps 3 Broadband Test & Measurement Fast Rise and Fall Times: 19 / 18 ps Programmable Differential Output Serial Data Transmission up to 14 Gbps Voltage Swing: 600 - 1100 mVp-p Clock Buffering up to 14 GHz Power Dissipation: 300 mW Single Supply: -3.3 V 16 Lead 3x3 mm SMT Package: 9 mm2 G eneral Description Functional Diagram The HMC720LP3E is a 1:2 Fanout Buffer designed to support data transmission rates up to 14 Gbps, and clock frequencies as high as 14 GHz. All differential inputs to the HMC720LP3E are CML and terminated on-chip with 50 Ohms to the positive supply, GND, and may be DC or AC coupled. Outputs can be connected directly to a 50 Ohm ground-terminated system or drive devices with CML logic input. The HMC720LP3E also features an ouput level control pin, VR, which allows for loss compensation or signal level optimization. The HMC720LP3E operates from a single -3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package. Electrical Specifi cations, T = +25 C, Vee = -3.3 V, VR = 0 V A Parameter Conditions Min.
