HMC729LC3C

HMC729LC3C v05.1010 26 GHz, T-TYPE FLIP-FLOP w/ RESET Features Supports Clock Frequencies up to 26 GHz Differential or Single-Ended Operation Fast Rise and Fall Times: 18 / 17 ps Low Power Consumption: 270 mW typ. Propagation Delay: 95 ps Single Supply: -3.3 V 16 Lead Ceramic 3x3 mm SMT Package: 9 mm2 Typical Applications The HMC729LC3C is ideal for: • Serial Data Transmission up to 26 Gbps 3 HIGH SPEED LOGIC - SMT • High Speed Frequency Divider (up to 26 GHz) • Broadband Test & Measurement • RF ATE Applications Functional Diagram General Description The HMC729LC3C is a T-Type 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 HMC729LC3C 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 HMC729LC3C operates from a single -3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
