... HIGH-PERFORMANCE, LOW-VOLTAGE PECL BUS CLOCK DRIVER & TRANSLATOR w/ INTERNAL TERMINATION DESCRIPTION The SY89825U is a High Performance Bus Clock Driver with 22 differential LVPECL output pairs. This part is designed for use in low voltage (2.5V, 3.3V) 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 LVDS or LVPECL by the CLK_SEL pin ...
