HMC748LC3C v01.1208 13 Gbps, 2:1 SELECTOR w/ PROGRAMMABLE OUTPUT VOLTAGE & POSITIVE SUPPLY HIGH SPEED LOGIC - SMT 7 Typical Applications Features The HMC748LC3C is ideal for: Supports High Data Rates: up to 13 Gbps • 2:1 Multiplexer up to 13 Gbps Single-ended inputs • RF ATE Applications Differential & Single-ended outputs • Broadband Test & Measurement Fast Rise and Fall Times: 22 / 22 ps • Serial Data Transmission up to 13 Gbps Low Power Consumption: 250 mW typ. • Redundant Path Switching Programmable Differential Output Voltage Swing: 600 - 1200 mV • Built-in Test Propagation Delay: 125 ps Single Supply: +3.3V 16 Lead Ceramic 3x3mm SMT Package: 9mm 2 Functional Diagram General Description The HMC748LC3C is a 2:1 Selector designed to support data transmission rates of up to 13 Gbps, and selector port operation of up to 13 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, which allows for loss compensation or for signal level optimization. All single-ended input signals to the HMC748LC3C are terminated with 50 ohms to Vcc on-chip, and may be either AC or DC coupled. The outputs of the HMC748LC3C may be operated either differentially or single-ended. 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 HMC748LC3C operates from a single +3.3V DC supply and is housed in a ceramic RoHS compliant 3x3 mm SMT package.
