Functional Description

The CY2309NZ is a low-cost buffer designed to distribute

high-speed clocks in mobile PC systems and desktop PC

systems with SDRAM support. The part has nine outputs, eight

of which can be used to drive two DIMMs or four SO-DIMMs, and

the remaining can be used for external feedback to a PLL. The

device operates at 3.3V and outputs can run up to 133.33 MHz.

The CY2309NZ is designed for low EMI and power optimization.

It has multiple V

and V

pins for noise optimization and

consumes less than 32 mA at 66.6 MHz, making it ideal for the

low-power requirements of mobile systems. It is available in an

ultra-compact 150-mil 16-pin SOIC package.
