HMC744LC3 v03.0514 14 Gbps, FA sT RIsE TIME 1:2 FANOUT bUFFER w/ pROGRAMMAbLE OUTpUT VOLTAGE & pOsITIVE sUppLY Typical Applications Features The HMC744LC3 is ideal for: Inputs Terminated Internally to 50 Ohms RF ATE Applications Differential & Single-Ended Operation Broadband Test & Measurement Propagation Delay: 120 ps Serial Data Transmission up to 14 Gbps Fast Rise and Fall Times: 22 / 20 ps Programmable Differential Clock Buffering up to 14 GHz Output Voltage Swing: 600 - 1100 mV Low Power Consumption: 287 mW typ. Single Supply: +3.3 V 2 16 Lead Ceramic 3x3 mm SMT Package: 9 mm General Description Functional Diagram The HMC744LC3 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 HMC744LC3 are CML and terminated on-chip with 50 Ohms to the positive supply, Vcc, and may be AC or DC coupled. The differential CML outputs are source terminated to 50 Ohms and may also be AC or DC coupled. Outputs can be connected directly to a 50 Ohm Vcc-terminated system, while DC blocking capacitors may be used if the terminating system is 50 Ohms to ground. The HMC744LC3 also features an output level control pin, VR, which allows for loss compensation or signal-level optimization. the HMC744LC3 operates from a single 3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
