SY89809L 3.3V 1:9 HIGH-PERFORMANCE / LOW-VOLTAGE BUS CLOCK DRIVER

The SY89809L is a High-Performance Bus Clock Driver with 9 differential HSTL (High-Speed Transceiver Logic) 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 LVPECL (Lo.

Features

low pin-to-pin skew (50ps max.) and low part-to-part skew (200ps max.)—performance previously unachievable in a standard product having such a high number of outputs. The SY89809L is available in a single space saving package, enabling a lower overall cost solution. Datasheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
