The SY89827L is a High Performance Bus Clock
Driver with dual 1:10 or single 1:20 HSTL (High Speed
Transceiver Logic) output pairs. The part is designed for
use in low voltage (3.3V/1.8V) 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 HSTL or LVPECL (Low Voltage Positive Emitter
Coupled Logic) by the CLK_SEL pin. The Output Enables
(OE1 & OE2) are synchronous so that the outputs will only
be enabled/disabled when they are already in the LOW state.
This avoids any chance of generating a runt clock pulse
when the device is enabled/disabled as can happen with an
asynchronous control.
The SY89827L features extremely low skew performance
of <50ps over temperature and voltage –performance
previously unachievable in a standard product having such
a high number of outputs. The SY89827L is available in a
single space saving package, enabling a lower overall cost
solution. For applications that require greater HSTL fanout
capability, consider the SY89824L.
