PI6CUA878NFE

Overview

The PI6CUA878NFE is a zero-delay PLL clock driver manufactured by Diodes Incorporated, designed for 1.8V DDR2 memory applications. It operates within a supply voltage range of 1.7V to 1.9V and supports frequencies up to 410MHz. The device features one circuit with differential SSTL-18 input and output interfaces, providing a 1:10 frequency ratio. Packaged in a 52-VFBGA (4.5x7mm) surface-mount case, it functions between 0°C and +70°C.

Feature Summary

• Zero-delay PLL architecture for DDR2 memory clocking
• Differential SSTL-18 input/output signaling
• 1:10 frequency multiplication ratio
• Operates at 1.7V to 1.9V supply voltage

Applications

• DDR2 memory subsystems
• High-speed digital systems requiring low jitter clocking
• Embedded memory controllers

Procurement Notes

Verify the specific ordering suffix NFE against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Confirm current production status as previous similar models have reached end-of-life. Ensure compatibility with existing PCB footprint and thermal requirements for the 52-VFBGA package.

Selection Notes

Select this component when designing 1.8V DDR2 memory interfaces requiring a 1:10 clock multiplication. Verify that the system environment stays within the 0°C to +70°C operating temperature range. Ensure the design accommodates the 52-VFBGA package dimensions of 4.5x7mm.

Part Context

This part belongs to the PI6CU series of PLL clock drivers from Diodes Incorporated. It is specifically optimized for memory applications, differing from general-purpose clock generators by its focus on low jitter and specific voltage levels required for DDR2 standards.

Replacement Considerations

Check for direct pin-to-pin replacements within the PI6CU family. Verify if the PI6CU877NFE or similar variants meet the 410MHz frequency requirement and SSTL-18 interface needs.
