SSTVF16859BKLFT

Specialty Logic Overview

The SSTVF16859BKLFT is a DDR 13-bit to 26-bit registered buffer designed for DDR memory modules, including DDRI (PC1600, PC2100), DDR333 (PC2700), and DDRI-400 (PC3200). It operates with VDD between 2.3V and 2.7V for PC1600-PC2700 applications, or 2.5V to 2.7V for PC3200. The device supports low standby operation and features differential clock signals. All data inputs and outputs are SSTL_2 level compatible with JEDEC standards. It exceeds the performance of the SSTVN16859 and is available in a 56-pin VFQFPN package.
