The PI6C2510-133 is a low-noise phase-locked loop clock driver, distributing high-frequency clock signals for SDRAM and server applications. It features operating frequency up to 150 MHz, low-noise phase-locked loop clock distribution that meets 133 MHz Registered DIMM Synchronous DRAM modules for server/workstation/PC applications, allows clock input to have spread spectrum modulation for EMI reduction, zero input-to-output delay, low jitter, and on-chip phase-locked loop.
