We are developing Carrier board for Jetson Xavier 8GB module. The below are the quires,
1.We need two SATA ports in our application and we are planning to interface module with 88SE9182 IC using PCIEx2 (UPHY9 and UPHY 8) to fulfill the requirement. Will this work?
We need 2 Giga bit Ethernet ports. Since one Gb Ethernet(RGMII) is available from the module, we want to use WGI210IT IC to get one more port and for this we want to use PCIex1 (UPHY7), Will this work?
We want to use SAM-TECH SEAM connectors(Differential impedance 100 ohms) for interconnection between carrier board and IO board. CSI,USB3.1 , DP/HDMI and MDI signals will be routed through this connector. Since the 699 MOLEX connector (2048430001 , 92 ohms differential impedance) used for these signals on the jetson module, will it be a problem if we route these signals through SAM-TECH SEAM connector.
In OEM Product design guide trace impedance’s are given for all interfaces along with tolerance. Is it OK, if we design trace impedance’s with in the given tolerances.
We want to use XR17V532(PCIe to UART) IC to get more UART ports. Will there be any problems with this?
Can I order NVIDIA jetson evaluation kit with Jeston xavier 8GB module, please provide part number?
7.During uncontrolled power down, how does the Jetson xavier module behave. Does the module got internal capacitors or hold up circuit to maintain the internal rails for safe shutdown. From the OEM design guide, I came to know that the time required is 10 milli seconds after the VDDIN_PWR_BAD_N goes low.After VDDIN_PWR_BAD signal asserts to low (Due to loss of input), Should i maintain the rail voltage for 10 milli seconds in order to allow the safe shutdown?
