HMC858LC4B v04.0614 14 Gpbs, 2:1 DIFFERENTIAL SELECTOR WITH PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC858LC4B is ideal for: Supports High Data Rates: up to 14 Gbps 2:1 Multiplexer up to 14 Gbps Differential or Single-Ended Operation 16G Fiber Channel Fast Rise and Fall Times: 19 / 20 ps Serial Data Transmission up to 14 Gbps Low Power Consumption: 221 mW typ. Programmable Differential Redundant Path Switching Output Voltage Swing: 500 - 1300 mVp-p Built-in Test Propagation Delay: 87 ps Broadband Test & Measurement Single Supply: -3.3 V 2 24 Lead Ceramic 4x4 mm SMT Package: 16 mm Functional Diagram General Description The HMC858LC4B 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 differential inputs to the differential output upon assertion of the proper select port. The HMC858LC4B also features an output level control pin, VR, which allows for loss compensation or for signal level optimization. All differential input signals to the HMC858LC4B are terminated with 50 ohms to ground on-chip, and may be either AC or DC coupled. The outputs of the HMC858LC4B may be operated either differentially or single-ended. Outputs can be connected directly to a 50 ohm terminated system, while DC blocking capacitors may be used if the terminating system is 50 ohms to a non-ground DC voltage. The HMC- 858LC4B operates from a single -3.3V DC supply and is available in a ceramic RoHS-compliant, 4x4 mm SMT package.
