IDT, Integrated Device Technology Inc 8534AY-01LF

Description
The ICS853401 is a low skew, 1to22 Differentialto3.3V LVPECL Fanout Buffer. It has two selectable clock inputs: CLK, nCLK and PCLK, nPCLK. The CLK, nCLK pair can accept most standard differential input levels, including LVPECL, LVDS, LVHSTL, HCSL, and SSTL. The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input levels. The device is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the OE pin. The ICS853401's low output and parttopart skew characteristics make it ideal for workstation, server, and other highperformance clock distribution applications.
