184.108.40.206. Input to the FPGA from the LPDDR2 SDRAM Component
- read data
LPDDR2 SDRAM provides the flexibility to adjust drive strength to match the impedance of the memory bus, eliminating the need for termination voltage (VTT) and series termination resistors.
The programmable drive strength options are 34.3 ohms, 40 ohms (default), 48 ohms, 60 ohms, 80 ohms, and 120 ohms. You must perform board simulation to determine the best option for your board layout.
