HMC724LC3C v03.1010 HIGH SPEED LOGIC - SMT 3 14 Gbps FAST RISE TIME 1:2 FANOUT BUFFER Typical Applications Features The HMC724LC3C is ideal for: Inputs Terminated Internally to 50 Ohms • 16 G Fiber Channel Differential Inputs are DC Coupled • RF ATE Applications Propagation Delay: 110 ps • Broadband Test & Measurement Fast Rise and Fall Times: 19 / 18 ps • Serial Data Transmission up to 14 Gbps Power Dissipation: 300 mW • Clock Buffering up to 14 GHz 16 Lead Ceramic 3x3 mm SMT Package: 9 mm 2 Functional Diagram General Description The HMC724LC3C 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 and outputs are DC coupled and terminated on chip with 50 Ohm resistors to ground. The outputs may be used in either single ended or differential modes, and should be AC or DC coupled into 50 Ohm resistors connected to ground. All differential inputs to the HMC724LC3C are CML and terminated on-chip with 50 Ohms to the positive supply, GND, and may be DC or AC coupled. The differential CMl outputs are source terminated to to 50 Ohms and may also be AC or DC coupled. Outputs can be connected directly to a 50 Ohm ground-terminated system or drive devices with CML logic input. The HMC724LC3C operates from a single -3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
