Description
The ICS873991 is a low voltage, low skew, 3.3V LVPECL or ECL clock generator and a member of the HiPerClockS? family of High Performance Clock Solutions from IDT. The ICS873991 has two selectable clock inputs. The PCLK, nPCLK pair can accept an LVPECL input and the TEST_CLK pin can accept a LVCMOS or LVTTL input. ICS873991 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 ICS873991 to generate a multitude of different bank frequency ratios and output-to-input frequency ratios. The output frequency range is 25MHz to 400MHz and the input frequency range is 6.25MHz to 125MHz. The PLL_SEL input can be used to bypass the PLL for test and system debug purposes. In bypass mode, the input clock is routed around the PLL and into the internal output dividers.
