The SY89825U is a High Performance Bus Clock Driver
with 22 differential LVPECL output pairs. This part is
designed for use in low voltage (2.5V, 3.3V) applications
which require a large number of outputs to drive precisely
aligned, ultra low skew signals to their destination. The
input is multiplexed from either LVDS or LVPECL by the
CLK_SEL pin. The LVDS input includes a 100
internal
termination, thus eliminating the need for external
termination. The Output Enable (OE) is synchronous so
that the outputs will only be enabled/disabled when they
are already in the LOW state. This eliminates any chance
of generating a runt clock pulse when the device is enabled/
disabled as can happen with an asynchronous control.
The SY89825U features low pin-to-pin skew (35ps max.)
—performance previously unachievable in a standard
product having such a high number of outputs. The
SY89825U is available in a single space saving package
which provides a lower overall cost solution. In addition, a
single chip solution improves timing budgets by eliminating
the multiple device solution with their corresponding large
part-to-part skew.
