HMC850LC3TR

HMC850LC3 v03.0614 High Speed Logic - SMT 28 Gbps, 1:2 FANOUT BUFFER WITH PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC850LC3 is ideal for: Inputs Terminated Internally to 50 Ohms • RF ATE Applications Differential Inputs are DC Coupled • Broadband Test & Measurement Propagation Delay: 75 ps • Serial Data Transmission up to 28 Gbps Fast Rise and Fall Times: 16 / 15 ps • Clock Buffering up to 20 GHz Programmable Differential Output Voltage Swing: 600 - 1100 mV Power Dissipation: 315 mW 16 Lead Ceramic 3x3 mm SMT Package: 9 mm 2 Functional Diagram General Description The HMC850LC3 is a 1:2 Fanout Buffer designed to support data transmission rates up to 28 Gbps, and clock frequencies as high as 20 GHz. All differential inputs and outputs are DC coupled and terminated on chip with 50 Ohm resistors to the positive supply, ground. The outputs may be used in either singleended or differential modes, and should be AC or DC coupled into 50 Ohm resistors connected to ground. The HMC850LC3 also features an output level control pin, VR which allows for loss compensation or for signal level optimization. The HMC850LC3 operates from a single -3.3V DC supply and is available in a ceramic RoHS compliant 3x3 mm SMT package.
