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 2 DIMMs or 4 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
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.
