When an input clock signal is app- lied, divide-by-2 and divide-by-4 outputs are obser- ved simultaneously. All input signals to the HMC791- LC4B are terminated with 50Ω to ground on-chip, and may be either AC or DC coupled. Outputs can be connected directly to a 50Ω terminated system, while DC blocking capacitors must be used if the terminating system is 50Ω 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. 7 - 186 Electrical Specifications, TA = +25° C, Vee = Vee1 = Vee2 = Vee3 = -3.3V Parameter Power Supply Voltage Total Supply Current Input Frequency Input Amplitude Range (Single-Ended) [2] Input Return Loss Input High Voltage Input Low Voltage Conditions ±10% Tolerance 1.0 - 6 GHz 6 - 12 GHz 12 - 16 GHz 16 - 28 GHz <20 GHz GND Referenced GND Referenced Min. -3.0 0.1 -10 -20 -20 -20 -0.5 -1 Typ. -3.3 200 9 Max. -3.6 28 +6 +6 +3 +5 0.5 0 [1] See recommended single ended and differential configurations [2] See recommended single ended configuration.
