Cypress Semiconductor Corp CY2309NZSXC-1H

Description
The CY2309NZ is a lowcost buffer designed to distribute highspeed clocks in mobile and desktop PC systems with SDRAM support. It has nine outputs, eight of which can be used to drive two DIMMs or four SODIMMs, and the remaining can be used for external feedback to a PLL. The device operates at 3.3 V and outputs can run up to 133.33 MHz.
The CY2309NZ is designed for low EMI and power optimization. It has multiple Vss and Vop pins for noise optimization and consumes less than 32 mA at 66.6 MHz, making it ideal for the lowpower requirements of mobile systems. It is available in an ultracompact 150mil 16pin SOIC package.
