IDT, Integrated Device Technology Inc 854S057BGILF

Description
The 854S057B is a 4:1 or 2:1 LVDS Clock Multiplexer that operates up to 2GHz. It has four selectable PCLK, nPCLK inputs with internal termination and can accept most standard differential input levels (LVPECL, LVDS, CML, SSTL). The 854S057B operates using a 2.5V supply voltage and has a fully differential architecture with low propagation delay, making it ideal for highspeed multiplexing applications. The select pins have internal pulldown resistors, allowing the device to be configured as a 2:1 multiplexer by leaving one input unconnected. The SEL1 pin is the most significant bit, and the binary number applied to the select pins selects the corresponding data input.
