Description
AI
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.
