描述
The 844S2416 is a 17-output, dual-PLL frequency synthesizer optimized to generate a variety of clocks for Ethernet, USB, and other interfaces. Using a 25MHz 18pF parallel resonant crystal, the device will generate 24MHz, 25MHz, 100MHz, and 200MHz clocks with mixed HCSL and LVCMOS/LVTTL levels. The 844S2416 is packaged in a 56-pin VFQFN package that is optimum for applications with space limitations.
