| HMC745LC3C v01.1208 13 Gbps, FAST RISE TIME XOR / XNOR GATE w/ PROGRAMMABLE OUTPUT VOLTAGE & POSITIVE SUPPLY Typical Applications The HMC745LC3C is ideal for: * RF ATE Applications Features Inputs Terminated Internally in 50 Ohms Differential & Singe-Ended Operation Fast Rise and Fall Times: 21 / 19 ps Low Power Consumption: 240 mW typ. Programmable Differential Output Voltage Swing: 600 - 1200 mV Propagation Delay: 95 ps Single Supply: +3.3V 16 Lead Ceramic 3x3mm SMT Package: 9mm 2 7 HIGH SPEED LOGIC - SMT * Broadband Test & Measurement * Serial Data Transmission up to 13 Gbps * Digital Logic Systems up to 13 GHz Functional Diagram General Description The HMC745LC3C is a XOR/XNOR gate function designed to support data transmission rates of up to 13 Gbps, and clock frequencies as high as 13 GHz. The HMC745LC3C 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 HMC745LC3C 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 HMC745LC3C operates from a single +3.3V DC supply, and is available in a ceramic RoHS compliant 3x3 mm SMT package.
