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
SS
and V
DD
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.
