HMC679LC3C v06.0514 26 GHz, T FLIP-FLOP w/ RESET & PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC679LC3C is ideal for: Supports Clock Frequencies up to 26 GHz Serial Data Transmission up to 26 Gbps Differential or Single-Ended Operation High Speed Frequency Divider (up to 26 GHz) Fast Rise and Fall Times: 18 / 17 ps Broadband Test & Measurement Low Power Consumption: 270 mW typ. Programmable Differential Output Voltage Swing: RF ATE Applications 600 - 1100 mVp-p Propagation Delay: 95 ps Single Supply: -3.3 V 2 16 Lead Ceramic 3 x 3 mm SMT Package: 9 mm Functional Diagram General Description The HMC679LC3C is a T Flip-Flop w/Reset desig- ned 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-by- two 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 HMC679LC3C are CML and terminated on-chip with 50 Ohms to the positive supply, GND, and may be DC or AC coupled. Outputs can be connected directly to a 50 Ohm ground-terminated system or drive devices with CML logic input. The HMC679LC3C also features an ouput level control pin, VR, which allows for loss compensation or signal level optimization. The HMC679LC3C operates from a single -3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package. Electrical Specifications, T = +25 C, Vee = -3.3 V, VR = 0 V A Parameter Conditions Min.
