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.
