HMC747LC3C v03.1010 14 Gbps, FAST RISE TIME D-TYPE FLIP-FLOP w/ PROGRAMMABLE OUTPUT VOLTAGE & POSITIVE SUPPLY HIGH SPEED LOGIC - SMT 3 Typical Applications Features The HMC747LC3C is ideal for: Supports High Data Rates: up to 14 Gbps • RF ATE Applications Differential & Singe-Ended Operation • Broadband Test & Measurement Fast Rise and Fall Times: 22 / 20 ps • Serial Data Transmission up to 14 Gbps Low Power Consumption: 264 mW typ. • Digital Logic Systems up to 14 GHz Programmable Differential Output Voltage Swing: 700 - 1300 mV Propagation Delay: 105 ps Single Supply: +3.3 V 16 Lead Ceramic 3x3 mm SMT Package: 9 mm 2 Functional Diagram General Description The HMC747LC3C is a D-Type Flip-Flop designed to support data transmission rates of up to 14 Gbps, and clock frequencies as high as 14 GHz. During normal operation, data is transferred to the outputs on the positive edge of the clock. Reversing the clock inputs allows for negative-edge triggered applications. All differential inputs to the HMC747LC3C are CML and terminated on-chip with 50 Ohms to the positive supply, Vcc, and may be AC or DC coupled. The differential CML outputs are source terminated to 50 Ohms and may also be AC or DC coupled. Outputs can be connected directly to a 50 Ohm Vcc-terminated system, while DC blocking capacitors may be used if the terminating system is 50 Ohms to ground. The HMC747LC3C also features an output level control pin, VR, which allows for loss compensation or signal-level optimazation. the HMC747LC3C operates from a single 3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
