描述
The 8440258-46 is an 8-output synthesizer optimized to generate Ethernet clocks. The device will generate 125MHz and 25MHz clocks from a 25MHz crystal with a very good jitter performance. The 8440258-46 uses Renesas' third-generation low phase noise VCO technology and is packaged in a small, 5mm x 5mm VFQFN package.
