HMC748LC3C v03.1010 14 Gbps, 2:1 SELECTOR w/ PROGRAMMABLE OUTPUT VOLTAGE & POSITIVE SUPPLY Typical Applications The HMC748LC3C is ideal for: • 2:1 Multiplexer up to 14 Gbps Features Supports High Data Rates: up to 14 Gbps Single-ended inputs Differential & Single-Ended Outputs Fast Rise and Fall Times: 22 / 22 ps Low Power Consumption: 250 mW typ. Programmable Differential Output Voltage Swing: 600 - 1200 mV Propagation Delay: 125 ps Single Supply: +3.3 V 16 Lead Ceramic 3x3 mm SMT Package: 9 mm 2 3 HIGH SPEED LOGIC - SMT • RF ATE Applications • Broadband Test & Measurement • Serial Data Transmission up to 14 Gbps • Redundant Path Switching • Built-in Test Functional Diagram General Description The HMC748LC3C is a 2:1 Selector designed to support data transmission rates of up to 14 Gbps, and selector port operation of up to 14 GHz. The selector routes one of the two single-ended inputs to the differential output upon assertion of the proper select port. The HMC748LC3C also features an output level control pin, VR, that allows for loss compensation or for signal level optimization. All select differential inputs to the HMC748LC3C are CML and terminated on-chip with 50 Ohms to the positive supply, Vcc, and may be AC or DC coupled. The single-ended inputs to the HMC748LC3C are CML terminated on-chip with 50 Ohms to the positive supply, GND, and may be 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 HMC748LC3C operates from a single + 3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
