QS5LV931
3.3V LOW SKEW CMOS PLL
CLOCK DRIVER WITH
INTEGRATED LOOP FILTER
DESCRIPTION:
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: Q
0
–Q
4
, Q/2. Careful layout and design ensure <300ps
skew between the Q
0
–Q
4
, and Q/2 outputs. The QS5LV931 includes
an internal RC filter which provides excellent jitter characteristics and
elimnates the need for external components. Various combinations of
feedback and a divide-by-2 in the VCO path allow applications to be
customzed 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 systemfor
guaranteed low skew, system-wide clock distribution networks. In the
QSOP package, the QS5LV931 clock driver represents the best value
in small formfactor, high-performance clock management products.

Note AN-227.
