The SY89828L is a precision fanout buffer with 20
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_SEL1
and CLK_SEL2 pins. The Output Enables (OE1 and 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 SY89828L 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 SY89828L is available in a single space saving package,
enabling a lower overall cost solution.
