PI6CUA878NFEX

Overview

The PI6CUA878NFEX 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 signals in a 1:10 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 clock generation
• Differential SSTL-18 input/output signaling
• 1:10 frequency division ratio
• Maximum operating frequency of 410MHz

Applications

• DDR2 memory subsystems
• High-speed digital logic synchronization
• System-on-chip clock distribution

Procurement Notes

Verify the specific suffix 'X' against official Diodes Incorporated documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Ensure the 52-VFBGA footprint matches the target PCB design constraints.

Selection Notes

Select this component when a low-jitter, zero-delay buffer is required for 1.8V DDR2 interfaces. The 1:10 ratio suits designs needing multiple synchronized outputs from a single source. Verify that the 410MHz maximum frequency meets system timing requirements and that the 0°C to 70°C industrial temperature range aligns with environmental conditions.

Part Context

This part belongs to the PI6CUA series of clock drivers optimized for memory applications. It complements other Diodes Incorporated timing solutions by providing precise phase alignment for high-speed data buses. The VFBGA package allows for compact board layouts in dense electronic systems.

Replacement Considerations

Check Diodes Incorporated cross-reference lists for direct pin-compatible alternatives. Verify if newer revisions of the PI6CUA878 series offer updated packaging or extended temperature ranges suitable for the application.
