UXN40M7K [Microchip]

The UXN40M7K is a programmable integer divider with divide ratios from 1 to 127. It features single-ended or differential inputs and outputs, CMOS and LVTTL compatible parallel control inputs, and is packaged in a 24-pin, 4 mm × 4 mm leadless ceramic surface mount package. Key specifications include a wide operating frequency range of 0.5 GHz to 40 GHz, large output swings (>600 mVpp/side), and low SSB phase noise of -153 dBc at 10 kHz offset. The device is suitable for high-frequency synthesizer applications, including fractional-N and integer-N PLLs.
