SY89828L

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 CLKSEL1 and CLKSEL2 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.
