| HMC791LC4B v00.0609 DIVIDE-BY-2, DIVIDE-BY-4 0.1 - 28 GHz Typical Applications The HMC791LC4B is ideal for: * Frequency Division up to 28 GHz Features Supports Clock Frequencies up to 28 GHz Simultaneous Divide-by-2 and Divide-by-4 Outputs Differential and Single-Ended Operation [1] Fast Rise and Fall Times (12 / 14 ps) Low Power Consumption: 660mW Single Negative Power Supply (-3.3V) Output Signal Swing: 600mV p-p Differential Ultra Low SSB Phase Noise: -151 dBc/Hz 24 Lead 4x4mm SMT Package: 16mm 2 7 HIGH SPEED LOGIC - SMT * Short, Intermediate, Long Haul Fiber Optic Applications * 100 GbE Applications * Serial Data Transmission Systems up to 28 GHz * Broadband Test and Measurement Applications Functional Diagram General Description The HMC791LC4B is a low-noise divide-by-2, divideby-4 designed to support input clock frequencies as high as 28 GHz. When an input clock signal is applied, divide-by-2 and divide-by-4 outputs are observed simultaneously. All input signals to the HMC791LC4B are terminated with 50 to ground on-chip, and may be either AC or DC coupled. Outputs can be connected directly to a 50 terminated system, while DC blocking capacitors must be used if the terminating system is 50 to a non-zero voltage. The HMC791LC4B operates from a single -3.3V DC supply and is available in a ceramic RoHS compliant SMT package.
