CY2309NZ Nine-Output 3.3V Buffer Features Functional Description • 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 • 8.7-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 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 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. • Space-saving 16-pin 150-mil SOIC package • 3.3V operation • Industrial temperature available Block Diagram Pin Configuration BUF_IN OUTPUT1 16 SOIC Top View OUTPUT2 BUF_IN OUTPUT1 1 16 OUTPUT3 2 15 OUTPUT2 VDD 3 OUTPUT4 14 4 13 GND OUTPUT3 OUTPUT4 VDD 5 12 6 11 7 10 8 9 OUTPUT5 OUTPUT6 OUTPUT9 OUTPUT8 OUTPUT7 VDD GND OUTPUT6 OUTPUT5 GND OUTPUT7 OUTPUT8 OUTPUT9 Pin Description for CY2309NZ Pin Signal Description 4, 8, 13 VDD 3.3V Digital Voltage Supply 5, 9, 12 GND Ground 1 BUF_IN Input Clock 2, 3, 6, 7, 10, 11, OUTPUT [1:9] 14, 15, 16 Cypress Semiconductor Corporation Document #: 38-07182 Rev. *C Outputs • 3901 North First Street • San Jose, CA 95134 • 408-943-2600 Revised February 24, 2004 CY2309NZ Storage Temperature ................................. –65°C to +150°C Maximum Ratings Junction Temperature ................................................. 150°C Supply Voltage to Ground Potential ............... –0.5V to +7.0V Static Discharge Voltage (per MIL-STD-883, Method 3015) ............................ >2,000V DC Input Voltage (Except REF) ............–0.5V to VDD + 0.5V DC Input Voltage REF......................................... –0.5V to 7V Operating Conditions for Commercial and Industrial Temperature Devices Parameter Description Min.
