HMC858LC4B v01.0111 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. • Redundant Path Switching Programmable Differential Output Voltage Swing: 500 - 1300 mVp-p • Built-in Test ik C row ey o a C nfid ve or e C po nt o ra ial rpo tio ra n tio U n se O nl y Typical Applications Propagation Delay: 87 ps • Broadband Test & Measurement Single Supply: -3.3 V 24 Lead Ceramic 4x4 mm SMT Package: 16 mm2 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. ic 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 HMC858LC4B operates from a single -3.3V DC supply and is available in a ceramic RoHS-compliant 4x4 mm SMT package.

Signal lines should have 50 Ohm impedance while the package ground leads should be connected directly to the ground plane similar to that shown. The exposed package base should be connected to Vee. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request. Install jumper on JP1 to short VR to GND for normal operation.
