AD9548BCPZ Quad and Octal Input Network Clock Generator or Synchronizer IC

The AD9548 provides synchronization for many systems, including synchronous optical networks (SONET/SDH). The AD9548 generates an output clock synchronized to one of up to four differential or eight single-ended external input references. The digital PLL allows for reduction of input time jitter or phase noise associated with the external references. The AD9548 continuously generates a clean (low jitter), valid output clock even when all references have failed by means of a digitally controlled loop and holdover circuitry. The AD9548 operates over an industrial temperature range of −40°C to +85°C

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.
