Device Overview

Summary

The SY89809AL is a high-performance bus clock driver with nine differential High-Speed Transceiver Logic (HSTL) output pairs. The part is designed for use in low-voltage (3.3V/1.8V) applications, which require a large number of outputs to drive precisely aligned, ultra-low skew signals to their destination. The input is multiplexed from either HSTL or Low-Voltage Positive-Emitter-Coupled Logic (LVPECL) by the CLK_SEL pin. The Output Enable (OE) 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 SY89809AL features low pin-to-pin skew (15ps typical) and low part-to-part skew (100ps typical). The SY89809AL is available in a single space-saving package, enabling a lower overall cost solution.
