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
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 3.3 V and outputs can run up to 133.33 MHz.
■ Supports two DIMMs or four SO-DIMMs with one additional
output for feedback to an external or chipset phase-locked loop
(PLL)
■ 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 VSS and VDD 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.
■ 1-ns input-output delay
■ Buffers all frequencies from 2 MHz to 133.33 MHz
■ Output-output skew less than 250 ps

■ Multiple VDD and VSS pins for noise and electromagnetic
interference (EMI) reduction
■ Space-saving 16-pin 150-mil small-outline integrated circuit
(SOIC) package
■ 3.3-V operation
■ Industrial temperature available
