< 50ps ch-ch skew
■ LVDS input includes 100
internal termination
■ Low supply voltage: 2.5V, 3.3V
■ –40°C to +85°C temperature range
■ Output enable (OE) pin
■ Available in 64 EPAD-TQFP
The SY89829U is a High Performance dual 1:10 or
single 1:20 LVPECL Clock Driver. The 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 inputs include a 100 internal termination across
the input pair, thus eliminating any need for external
termination. The 2:1 input mux makes this device an ideal
choice for redundant clock applications that need to switch
between two reference clocks. 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 SY89829U features low pin-to-pin skew (50ps max.)
and low part-to-part skew (200ps max.)—performance
previously unachievable in a standard product having such
a high number of outputs. The SY89829U 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.
