.. ZL40812 10GHz Fixed Modulus ÷ 16 Data Sheet Features - - - - - - Very High Operating Speed Operation down to DC with Square Wave Input Low Phase Noise (Typically better than 152d Bc/Hz at 10k Hz) 5V Single Supply Operation Low Power Dissipation: 500m W (Typ) Surface Mount Plastic Package With Exposed Pad (See Application Notes July 2003 Ordering Information ZL40812/DCE (tubes) 8 lead e-pad SOIC ZL40812/DCF (tape and reel) 8 lead e-pad SOIC -40 ° C to +85 ° C Description Description The ZL40812 is one of a range of 5V supply, very high speed low power prescalers for professional applications with a fixed modulus of divide by 16. The dividing elements are static D type flip flops and therefore allow operation down to DC if the drive signal is a pulse waveform with fast risetimes. The output stage has internal 50 ohm pull up giving a 1V pp output. See application notes for more details.
