AD9517-3ABCPZ 12-Output Clock Generator withIntegrated 2.0 GHz VCO

AD9517-3 series GENERAL DESCRIPTION

The AD9517-31 provides a multi-output clock distribution

function with subpicosecond jitter performance, along with an

on-chip PLL and VCO. The on-chip VCO tunes from 1.75 GHz

to 2.25 GHz. Optionally, an external VCO/VCXO of up to

2.4 GHz can be used.

The AD9517-3 emphasizes low jitter and phase noise to

maximize data converter performance, and it can benefit other

applications with demanding phase noise and jitter requirements.

Product Attributes

Koben Electronics was founded in 1995 and is located in the Silicon Valley of China, Shenzhen. 

The mission of Koben has always been to provide quality electronics components to manufacturers worldwide. Early on we became a primary conduit for end-of-program and overstock inventory for major distributors such as Future Electronics and contract manufacturers as Flextronics. Koben has since then added sourcing of high quality components from local manufacturers in China.

Koben has always been customer driven rather than opportunity driven. Meaning- we will always choose path that is best for long term relationship with customer over short term view. It is why we have one of the highest customer retention scores of China based distributors.
