HMC728LC3C

HMC728LC3C v04.1010 14 Gbps, 2:1 SELECTOR Typical Applications The HMC728LC3C is ideal for: • 2:1 Multiplexer up to 14 Gbps Features Supports High Data Rates: up to 14 Gbps Single-Ended Inputs Differential or Single-Ended Outputs Fast Rise and Fall Times: 17 / 15 ps Low Power Consumption: 250 mW typ. Propagation Delay: 125 ps Single Supply: -3.3 V 16 Lead Ceramic 3x3 mm SMT Package: 9 mm 2 3 HIGH SPEED LOGIC - SMT • RF ATE Applications • Broadband Test & Measurement • Serial Data Transmission up to 14 Gbps • Redundant Path Switching • Built-in Test 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.

HMC728LC3C High Speed Logic, 2:1 Selector 122518 Evaluation Board [1] Reference this number when ordering complete evaluation PCB [2] Circuit Board Material: Arlon 25FR or 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 GND. 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 HMC728LC3C v04.1010 14 Gbps, 2:1 SELECTOR 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
