HMC728LC3C v04.1010 HIGH SPEED LOGIC - SMT 3 14 Gbps, 2:1 SELECTOR Typical Applications Features The HMC728LC3C 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 or Single-Ended Outputs • Broadband Test & Measurement Fast Rise and Fall Times: 17 / 15 ps • Serial Data Transmission up to 14 Gbps Low Power Consumption: 250 mW typ. • Redundant Path Switching Propagation Delay: 125 ps • Built-in Test Single Supply: -3.3 V 16 Lead Ceramic 3x3 mm SMT Package: 9 mm 2 Functional Diagram General Description The HMC728LC3C 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. All differential inputs to the HMC728LC3C are CML and terminated on-chip with 50 Ohms to the positive supply, GND, and may be DC or AC coupled. The differential CMl outputs are source terminated to to 50 Ohms and may also be AC or DC coupled. Outputs can be connected directly to a 50 Ohm ground-terminated system or drive devices with CML logic input. The HMC728LC3C operates from a single -3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
