CY2309NZ
Nine-Output 3.3 V Buffer
Nine-Output 3.3 V Buffer
Features Functional Description
One-input to nine-output buffer/driver The CY2309NZ is a low-cost buffer designed to distribute
high-speed clocks in mobile PC systems and desktop PC
Supports two DIMMs or four SO-DIMMs with one additional
systems with SDRAM support. The part has nine outputs, eight
output for feedback to an external or chipset phase-locked loop
of which can be used to drive two DIMMs or four SO-DIMMs, and
(PLL)
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.
Low power consumption for mobile applications
Less than 32 mA at 66.6 MHz with unloaded outputs The CY2309NZ is designed for low EMI and power optimization.
It has multiple V and V pins for noise optimization and
SS DD
1-ns Input-output delay
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
