SY89874U Description
This low-skew, low-jitter device is capable of accepting a high-speed (e.g., 622 MHz or higher) CML, LVPECL, LVDS, or HSTL clock input signal and dividing down the frequency using a programmable divider ratio to create a frequency-locked, lower speed version of the input clock. Available divider ratios are 2, 4, 8, and 16, or straight pass-through. In a typical 622 MHz clock system this would provide availability of...
