UXM15P Microchip

UXM15P DC-15 GHz Programmable Integer-N Prescaler Application Features The UXM15P can be used as a general Wide Operating Range: purpose, fixed modulus prescaler in high DC-20 GHz for Div-by-2/4/8 frequency PLLs. The multi-modulus mode DC-15 GHz for Div-by-4/5/6/7/8/9 of the device allows it to be used in phase Low SSB Phase Noise: -153 dBc locked loops such as integer-N and 10 kHz fractional-N architectures. The low phase Large Output Swings: >1 Vppk/side noise of the divider makes it ideal for Single-Ended and/or Differential generating low jitter, synchronous clocks Operation in telecom applications. Low power consumption: 0.6 W 4x4 QFN package Pad Metallization Parallel Control Lines The QFN package pad metallization consists of a Ni/Pd/Au plating over a Cu(c194) Description leadframe. The UXM15P is a low noise programmable divider featuring a binary divide-by-2/4/8 mode and multi-modulus divide-by-4/5/6/7/8/9 mode. The device features differential inputs and outputs, adjustable output swing and high input sensitivity. The control inputs are CMOS and LVTTL compatible. The UXM15P is packaged in a 24 pin, 4x4 mm leadless surface mount package.
