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 optimi-
zation. It has multiple V
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.
