The SSTL_15 pad set supports bidirectional single-ended and differential SSTL_15 signaling. The driver/receiver pairs, with embedded power cells, are supplied with a full complement of calibration, voltage reference, power, spacer, and adapter cells to assemble a pad ring by abutment. An ...
I get a problem about SSTL-15 interface circuit.As it's established by JEDEC,I search for this standard in JEDEC.But what I get are SSTL-2 and SSTL-18.They are working for DDR1 and DDR2.There is no SSTL-15 in JEDEC.So I need your help ! Best regards Lich_Wang Translate Tags: ...

On the AC701 board, I was surprised to see the DDR sysclk inputs, (IO standard = DIFF_SSTL15, VCCO = 1.5V) driven by a LVDS oscillator without ac coupling. In UG471 (7series selectIO)page 90 it says: It is acceptable to have
在AC701板上,我惊讶地看到DDR sysclk输入(IO标准= DIFF_SSTL15,VCCO = 1.5V)由LVDS振荡器驱动而没有交流耦合。 在UG471(7系列selectiO)第90页中,它说: 在I / O bank中有差分输入,如LVDS和LVDS_25是可以接受的 除了那些输出所需的标称电压之外的电压电平 标准(LVDS输出为1.8V,LVDS_25输出为2.5V)。 但...
