HMC859LC3 v02.0914 26 GHz, DIVIDE-BY-8 WITH RESET & PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC859LC3 is ideal for: Supports Clock Frequencies up to 26 GHz High Speed Frequency Divider (up to 26 GHz) Differential or Single-Ended Operation Clock Synthesis Fast Rise and Fall Times: 19 / 17 ps Phase Locked Loops Low Power Consumption: 320 mW typ. Programmable Differential Broadband Test & Measurement Output Voltage Swing: 800 - 1900 mVp-p Propagation Delay: 146 ps Single Supply: -3.3 V 2 16 Lead Ceramic 3x3 mm SMT Package: 9 mm Functional Diagram General Description The HMC859LC3 is a Divide-by-8 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. 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 HMC859LC3 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 HMC859LC3 also features an ouput level control pin, VR, which allows for loss compensation or signal level optimization. The HMC859LC3 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. Typ.
