The SY89828L is a high-performance dual 1:10 fanout buffer designed for 3.3V applications, featuring 20 differential LVDS output pairs. It supports input multiplexing from both LVDS and LVPECL sources, allowing for flexible integration in various systems. The device guarantees a maximum frequency of over 1GHz and maintains a low pin-to-pin skew of less than 50ps, ensuring precise signal alignment. Additionally, it offers low jitter performance with less than 1ps RMS cycle-to-cycle jitter and less than 1ps peak-to-peak total jitter. The SY89828L includes synchronous output enable functions to prevent runt clock pulses during transitions and features internal termination for LVDS inputs. It is packaged in a 64-Pin EPAD-TQFP, making it suitable for space-constrained designs. This product is ideal for applications in enterprise networking, high-end servers, and communications systems.
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.
