UXD20P [Microchip]

The UXD20P is a low noise DC to 20GHz programmable prescaler with divide-by-1, divide-by-2, divide-by-4, or divide-by-8 division ratios. In divide-by-1 mode, it functions as a DC-7 GHz limit amplifier. The device features differential inputs and outputs, adjustable output swing, high input sensitivity, and CMOS/LVTTL compatible control inputs. It is packaged in a 24 pin, 4 mm x 4 mm leadless surface mount QFN package. Key features include wide operating range (DC-20 GHz), low SSB phase noise, large output swings (750 mVpp/side), single-ended and/or differential operation, low power consumption (430 mW), and 3 dividers-in-one with pass-through capability.
