GENERAL DESCRIPTION
Along with a fully integrated PLL, the ICS87931I contains frequency configurable outputs and an external feedback input for regenerating clocks with “zero delay”. ,&6 Selectable clock inputs, CLK1 and differential CLK0, nCLK0 support redundant clock applications. The output divider values of Bank A, B and C are controlled by the DIV_SELA, DIV_SELB and DIV_SELC, respectively. For test and system debug purposes, the PLL_SEL input allows the PLL to be bypassed.
