QS5917T
LOW SKEW CMOS PLL
CLOCK DRIVER WITH
INTEGRATED LOOP FILTER
DESCRIPTION
The QS5917T Clock Driver uses an internal phase locked loop (PLL)
to lock low skew outputs to one of two reference clock inputs. Eight
outputs are available: Q0-Q4, 2xQ, Q/2, Q5. Careful layout and design
insures < 500ps skew between the Q0-Q4, and Q/2 outputs. The QS5917T
includes an internal RC filter which provides excellent jitter characteris-
tics and eliminates the need for external components. In addition, TTL
level outputs reduce clock signal noise. Various combinations of feed-
back and a divide-by-2 in the VCO path allow applications to be custom-
ized for linear VCO operation over a wide range of input SYNC fre-
quencies. The VCO can also be disabled by the PLL_EN signal to allow
low frequency or DC testing. The LOCK output asserts to indicate when
phase lock has been achieved. The QS5917T is designed for use in
high-performance 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 distri-
bution networks.

Note AN-227.
