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.
