HMC748LC3C v05.0514 14 Gbps, 2:1 SELECTOR w/ PROGRAMMABLE OUTPUT VOLTAGE & POSITIVE SUPPLY Typical Applications Features The HMC748LC3C is ideal for: Supports High Data Rates: up to 14 Gbps 2:1 Multiplexer up to 14 Gbps Single-ended inputs RF ATE Applications Differential & Single-Ended Outputs Broadband Test & Measurement Fast Rise and Fall Times: 22 / 22 ps Low Power Consumption: 250 mW typ. Serial Data Transmission up to 14 Gbps Programmable Differential Redundant Path Switching Output Voltage Swing: 600 - 1200 mV Built-in Test Propagation Delay: 125 ps Single Supply: +3.3 V 2 16 Lead Ceramic 3x3 mm SMT Package: 9 mm General Description Functional Diagram The HMC748LC3C is a 2:1 Selector designed to sup- port 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. Electrical Specifications, T = +25 C, Vcc = 3.3 V, VR = 3.3 V A Parameter Conditions Min.
