Part Number:AM5718
Tool/software: Code Composer Studio
Hi.
My customers are looking at the AM57xx Schematic checklist.(sprack7a.pdf)
Question 1:
2.7.5 If PCIe is not Used, "a common filter element" is written.
In 2.7.4 and 2.7.6, "a filter element" is written.
What is the difference between "a common filter element" and "a filter element"?
(Simply using the same filter for VDDA_PCIE, VDDA_PCIE0 and VDDA_PCIE1?)
Question 2:
The following is described in 2.11 DDR3.
DDR_RESET should be connected directly between the AM57xx devices and the SDRAMs. Addition of a pull-down resistor is also recommended. "Do not connect DDR_RESET to VTT termination resistors.
Would you tell me the recommended value for the pull-down resistor?
Question 3:
The following is described in 2.20 JTAG and EMU.
“Clock buffering is strongly recommended even for single device implementations”
Does "Clock" mean both of TCK and RTCK?
Or is it only TCK?
Regards,
Rei
