HMC749LC3C v04.1010 26 GHz, T FLIP-FLOP w/ RESET, PROGRAMMABLE OUTPUT VOLTAGE & POSITIVE SUPPLY Typical Applications The HMC749LC3C is ideal for: • Serial Data Transmission up to 26 Gbps Features Supports Clock Frequencies up to 26 GHz Differential & Single-Ended Operation Fast Rise and Fall Times: 18 / 17 ps Low Power Consumption: 270 mW typ. Programmable Differential Output Voltage Swing: 600 - 1100 mV Propagation Delay: 95 ps Single Supply: 3.3 V 16 Lead Ceramic 3x3 mm SMT Package: 9 mm2 3 HIGH SPEED LOGIC - SMT • High Speed Frequency Divider (up to 26 GHz) • Broadband Test & Measurement • RF ATE Applications Functional Diagram General Description The HMC749LC3C is a T Flip-Flop w/Reset designed to support clock frequencies as high as 26 GHz. During normal operation, with the reset pin not asserted, the output toggles from its prior state on the positive edge of the clock. This results in a divide-bytwo function of the clock input. Asserting the reset pin forces the Q output low regardless of the clock edge state (asynchronous reset assertion). Reversing the clock inputs allows for negative-edge triggered applications. All differential inputs to the HMC749LC3C 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 HMC749LC3C also features an output level control pin, VR, which allows for loss compensation or signal-level optimazation. the HMC749LC3C operates from a single 3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
