123585-HMC959LC3

HMC959LC3 v00.0910 HIGH SPEED LOGIC - SMT 3 26 GHz, DIVIDE-BY-4 WITH RESET & PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC959LC3 is ideal for: Supports Clock Frequencies up to 26 GHz • High Speed Frequency Divider (up to 26 GHz) Differential or Single-Ended Operation • Broadband Test & Measurement Fast Rise and Fall Times: 19 ps • Clock Synthesis Low Power Consumption: 281 mW typ. • Phase Locked Loops Programmable Differential Output Voltage Swing: 800 - 1800 mVp-p Propagation Delay: 121 ps Single Supply: -3.3 V 16 Lead Ceramic 3x3 mm SMT Package: 9 mm2 Functional Diagram General Description The HMC959LC3 is a Divide-by-4 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-byfour 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 HMC959LC3 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 HMC959LC3 also features an output level control pin, VR, which allows for loss compensation or signal level optimization. The HMC959LC3 operates from a single -3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
