SSTV16857D - Brand New Texas Instruments Special Logic ICs
-
Description
The SSTV16857 is a 14-bit SSTL_2 registered driver with differential clock inputs, designed to operate between 2.3 V and 2.7 V. It is intended to be incorporated into standard DIMM (Dual In-Line Memory Module) designs defined by JEDEC, such as DDR (Double Data Rate) SDRAM or SDRAM II Memory Modules. Unlike traditional SDRAM, DDR SDRAM transfers data on both clock edges (rising and falling), doubling the peak bus bandwidth. The SSTV16857 is intended to be used for SSTL_2 input and output signals. It supports class I outputs, which can be used for standard stub-series applications or capacitive loads. The device data inputs consist of differential receivers. The clock input is fully differential to be compatible with DRAM devices installed on the DIMM. The device also supports an asynchronous reset input pin to provide defined outputs even before a stable clock is supplied.
