HMC744LC3C v03.1209 13 Gbps, FAST RISE TIME 1:2 FANOUT BUFFER w/ PROGRAMMABLE OUTPUT VOLTAGE & POSITIVE SUPPLY HIGH SPEED LOGIC - SMT 3 Typical Applications Features The HMC744LC3C is ideal for: Inputs Terminated Internally in 50 Ohms • RF ATE Applications Differential & Single-Ended Operation • Broadband Test & Measurement Propagation Delay: 120 ps • Serial Data Transmission up to 13 Gbps Fast Rise and Fall Times: 22 / 20 ps • Clock Buffering up to 13 GHz Programmable Differential Output Voltage Swing: 600 - 1100 mV Low Power Consumption: 287 mW typ. Single Supply: +3.3V 16 Lead Ceramic 3x3mm SMT Package: 9mm2 General Description Functional Diagram The HMC744LC3C is a 1:2 Fanout Buffer designed to support data transmission rates up to 13 Gbps, and clock frequencies as high as 13 GHz. The HMC744LC3C also features an output level control pin, VR, which allows for loss compensation or for signal level optimization. All input and output signals to the HMC744LC3C are terminated with 50 Ohms to Vcc on-chip, and may be either AC or DC coupled. Inputs or outputs can be connected directly to a 50 Ohm to Vcc terminated system, while DC blocking capacitors may be used if the terminating system is 50 Ohms to ground. The HMC744LC3C operates from a single +3.3V DC supply, and is available in a ceramic RoHS compliant 3x3 mm SMT package.
