873990AYLFT - Renesas Electronics
Description: The 873990 is a low voltage, low skew, 3.3V LVPECL/ ECL Clock Generator. The 873990 has two selectable clock inputs. The XTAL1 and XTAL2 are used to interface to a crystal and the TEST_CLK pin can accept a LVCMOS or LVTTL input. This device has a fully integrated PLL along with frequency configurable outputs. An external feedback input and output regenerates clocks with "zero delay". The four independent banks of outputs each have their own output dividers, which allow the device to generate a multitude of
