WebThe DDR PHY has a pseudo-synchronous FIFO that transfers read data from the DQS clock domain to its internal clock domain. The DDR PHY read latency defines how long the DDR PHY should wait before reading the FIFO using internal clock, after it has been written by the DQS clock during reads. WebSep 27, 2006 · The specification, available for download at DDR is being developed by expert contributors from recognized leaders in the semiconductor, IP and electronic …
WebNov 18, 2016 · We have a custom board for AM3357 processor similar to EVM but slight difference in DDR3, We used MT41K512M16HA-107 DDR3L device from Micron, We … WebThe physical DDR3 interface on the KeyStone I DSPs is often called the DDR3 PHY. It includes the I/O buffers and all of the logic required to support the DDR3 interface technology. The DDR3 interface circuitry also includes registers and control logic to support the physical DDR3 interface as well as control for the DRAM devices.
WebThe DDR datasheet shows CL=6, CWL=5 for a tCK of 2.5ns - 3.3ns. CL=5 is not valid for 400MHz (2.5ns cycle time) -In DDR Timings, tXS should have a value of 270ns Make the changes above and test with that configuration. Definitely, you should be working with INVERT_CLKOUT=1 and EXT_PHY_CTRL_1 = 0x40100 WebThe DDR clock speed is configured in u-boot/board/ti/am335x/board.c file, check functions: get_dpll_ddr_params () sdram_init () How do you define that you are running at 303MHz? "But the amount of EE has not changed, the same is 300 CLK。 " - what does this mean? Regards, Pavel Egbert Liu over 4 years ago in reply to Pavel Botev
WebOur Board Design consist of 72-bit (64-bit plus ECC) single-rank DDR3 DRAM topology using x16 DRAMs. For DSP1, DSP2, DSP4 the DDR3 is Working Fine.
