HMC678LC3C

HMC678LC3C v04.1209 13 Gbps, 2:1 SELECTOR w/ PROGRAMMABLE OUTPUT VOLTAGE Features Supports High Data Rates: up to 13 Gbps Single-ended inputs Differential & Single-ended outputs Fast Rise and Fall Times: 19 / 18 ps Low Power Consumption: 250 mW typ. Programmable Differential Output Voltage Swing: 600 - 1200 mV Propagation Delay: 125 ps Single Supply: -3.3V 16 Lead Ceramic 3x3mm SMT Package: 9mm2 Typical Applications The HMC678LC3C is ideal for: • 2:1 Multiplexer up to 13 Gbps 3 HIGH SPEED LOGIC - SMT • RF ATE Applications • Broadband Test & Measurement • Serial Data Transmission up to 13 Gbps • Redundant Path Switching • Built-in Test Functional Diagram General Description The HMC678LC3C 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 HMC678LC3C 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 HMC678LC3C are terminated with 50 Ohms to ground on-chip, and may be either AC or DC coupled. The outputs of the HMC678LC3C 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 HMC678LC3C operates from a single -3.3V DC supply and is available in a ceramic RoHS compliant 3x3 mm SMT package.

HMC678LC3C High Speed Logic, 2:1 Selector 118775 Evaluation Board [1] Reference this number when ordering complete evaluation PCB [2] Circuit Board Material: Rogers 4350 The circuit board used in the application should use RF circuit design techniques. 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. 3-7 F or price, delivery and to place orders: Hittite Microwave Corporation, 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or apps@hittite.com HMC678LC3C v04.1209 13 Gbps, 2:1 SELECTOR w/ PROGRAMMABLE OUTPUT VOLTAGE Application Circuit 3 HIGH SPEED LOGIC - SMT F or price, delivery and to place orders: Hittite Microwave Corporation, 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or apps@hittite.com 3-8
