SSTV16859DGG,118

Specialty Logic Overview

The SSTV16859DGG,118 is a 2.5 V 13-bit to 26-bit SSTL_2 registered buffer designed for stacked DDR DIMM applications. It operates within a supply voltage range of 2.3 V to 2.7 V and supports clock frequencies up to 200 MHz. The device features a flow-through architecture with differential clock inputs (CK and CK) and an asynchronous LVCMOS reset pin. Propagation delay from clock to output is typically 2.4 ns at 2.5 V with a 30 pF load. It is housed in a 64-pin plastic thin shrink small outline package (SOT-646).

Specialty Logic Feature Summary

• Optimized for stacked DDR SDRAM applications using Stub-Series Terminated Logic (SSTL_2)
• Flow-through architecture facilitates optimized PCB layout
• Supports efficient low-power standby operation via asynchronous reset
• Provides high ESD protection exceeding 2000 V per HBM method A114

Specialty Logic Applications

• Stacked DDR Double Data Rate SDRAM memory modules
• JEDEC compliant Dual In-Line Memory Module (DIMM) designs
• Registered buffer circuits for high-speed data transmission

Specialty Logic Procurement Notes

Verify component authenticity through authorized NXP Semiconductors distributors or official channels. Confirm the specific ordering suffix matches the required package type, as multiple packages including TSSOP, LFBGA, and HVQFN are available. Ensure compliance with JEDEC standards for the intended memory application.

Specialty Logic Selection Notes

Select this component when designing registered buffers for stacked DDR DIMMs requiring SSTL_2 signaling. Ensure the system operates within the 2.3 V to 2.7 V supply range. Verify that the 200 MHz maximum clock frequency meets the target data rate requirements. Consider the 64-pin TSSOP package availability if space constraints align with its dimensions.

Specialty Logic Part Context

This part belongs to the SSTV series of logic ICs manufactured by NXP Semiconductors (formerly Philips Semiconductors). It is specifically engineered for memory interface applications, complementing other parts like the SSTV16857 for unstacked DIMMs. The device integrates into standard JEDEC-defined memory module architectures.

Specialty Logic Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult the manufacturer's documentation for potential obsolescence management or cross-reference options.
