The SY89826L is a precision fanout buffer with 22
differential LVDS (Low Voltage Differential Swing) output
pairs. The part is designed for use in low voltage 3.3V
applications that 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 (Low
Voltage Positive Emitter Coupled Logic) by the CLK_SEL
pin. The OE (Output Enable) is 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 SY89826L features a low pin-to-pin skew of less
than 50ps—performance previously unachievable in a
standard product having such a high number of outputs.
The SY89826L is available in a single space saving package,
enabling a lower overall cost solution.
