SN74SSQE32882ZCJR

Specialty Logic Overview

The SN74SSQE32882ZCJR is a JEDEC SSTE32882-compliant registered buffer and differential clock PLL driver designed for DDR3 Registered DIMMs. It operates at VDD of 1.5V with an operating temperature range of 0°C to 85°C. The device features a 176-pin NFBGA package (drawing ZCJ, dimensions 6mm x 15mm) with a 0.65mm ball pitch in an 8x22 grid. It supports 28-bit to 56-bit data registering and includes address parity checking.

Specialty Logic Feature Summary

• Supports Quad Chip Select modes via QCSEN input for flexible system configurations
• Includes one-to-four pair differential clock PLL driver for optimized signal integrity
• Checks parity on command and address inputs to ensure data integrity
• Features optimal pinout for backside mounting and low crosstalk PCB layouts

Specialty Logic Applications

• DDR3 Registered DIMMs up to DDR3-1333
• Single-, dual-, and quad-rank RDIMM designs
• Stacked DDR3 DIMM architectures

Specialty Logic Procurement Notes

Verify the specific ordering suffix ZCJR against current Texas Instruments documentation to confirm availability status and packaging details. Confirm that the 176-pin NFBGA package drawing matches the required board layout constraints. Ensure design compliance with the specified 0°C to 85°C operating temperature range and 1.5V supply voltage requirements before finalizing procurement.

Specialty Logic Selection Notes

Select this component for high-density DDR3 memory applications requiring robust clock distribution and data buffering. The device supports single register backside mounting, which aids in reducing trace length and improving signal quality. Consider the specific package dimensions and ball pitch when designing the PCB footprint to ensure proper alignment with existing vias and routing layers.

Specialty Logic Part Context
