The QS5LV931 Clock Driver uses an internal phase locked loop (PLL) to lock low skew outputs to a reference clock input. Six outputs are available: Q0Q 4, Q/2. Careful layout and design ensure <300ps skew between the Q0Q4, and Q/2 outputs. The QS5LV931 includes an internal RC filter which provides excellent jitter characteristics and eliminates the need for external components. Various combinations of feedback and a divide-by-2 in the VCO path allow applications to be customized for linear VCO operation over a wide range of input SYNC frequencies. The PLL can also be disabled by the PLL_EN signal to allow low frequency or DC testing. The QS5LV931 is designed for use in cost sensitive high-performance computing systems, workstations, multi-board computers, networking hardware, and mainframe systems. Several can be used in parallel or scattered throughout a system for guaranteed low skew, system-wide clock distribution networks. In the QSOP package, the QS5LV931 clock driver represents the best value in small form factor, high-performance clock management products.
