CY2318ANZPVC-11

Application Specific Clock/Timing Overview

The CY2318ANZPVC-11 is a low-skew clock driver designed for distributing high-speed clocks in desktop PC applications. It features one input to 18 output buffers, supporting up to four SDRAM DIMMs with two additional outputs for feedback. Operating at 3.3V with LVCMOS/LVTTL inputs and LVCMOS outputs, it supports frequencies up to 100 MHz. The device includes a serial interface for individual output control and operates within a commercial temperature range of 0°C to 70°C.

Application Specific Clock/Timing Feature Summary

• One input to 18 output buffer/driver configuration
• Supports up to four SDRAM DIMMs with dedicated byte outputs
• Serial interface for individual output enable/disable control
• 150ps typical output-to-output skew

Application Specific Clock/Timing Applications

• Desktop PC motherboard clock distribution
• SDRAM DIMM clock buffering
• Pentium II processor system synchronization

Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix (e.g., -11 vs -11T) to confirm tape-and-reel packaging if required. Confirm lead-free status matches project requirements, as both standard and lead-free variants exist under similar part numbers. Ensure the 48-pin SSOP package aligns with PCB footprint specifications.

Application Specific Clock/Timing Selection Notes

Select this component when a single clock source must drive multiple SDRAM modules simultaneously. The serial interface allows dynamic control of individual output buffers, which is useful for power management or testing. Ensure the 3.3V supply voltage and 100 MHz maximum frequency meet the target memory controller requirements.

Application Specific Clock/Timing Part Context

This device is part of Cypress Semiconductor's Application Specific Clock/Timing family. It is specifically engineered as a buffer for desktop PCs, often used in conjunction with clock synthesizers like the CY2280 series to provide complete motherboard clock solutions.
