... General Description 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 ...

... July 2010 Operating Package Marking Range Commercial SY89809ALTZ with Pb-Free bar-line indicator Commercial SY89809ALTZ with Pb-Free bar-line indicator = 25°C, DC Electricals only. A 32-Pin TQFP (T32-1) Type Pin Function Differential clock input selected by CLK_SEL. Can be left floating if not selected. Floating input, if selected, produces a LOW at HSTL_CLK and a HSTL Input HIGH at /HSTL_CLK. HSTL input signal requires external termination 50Ω ...
