| CY2309NZ Nine-Output 3.3V Buffer Features 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 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. One-input to nine-output buffer/driver Supports two DIMMs or four SO-DIMMs with one additional output for feedback to an external or chipset PLL Low power consumption for mobile applications Less than 32 mA at 66.6 MHz with unloaded outputs 1-ns Input-Output delay Buffers all frequencies from DC 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 SOIC package 3.3V operation Industrial temperature available Logic Block Diagram BUF_IN OUTPUT1 OUTPUT2 OUTPUT3 OUTPUT4 OUTPUT5 OUTPUT6 OUTPUT7 OUTPUT8 OUTPUT9 Cypress Semiconductor Corporation Document #: 38-07182 Rev. *E * 198 Champion Court * San Jose, CA 95134-1709 * 408-943-2600 Revised September 23, 2008 [+] Feedback CY2309NZ Pinouts Figure 1.
