AM62A3: Minimal Design V3Link+ETH+HDMI

Betul Aktepe

Part Number: AM62A3
Other Parts Discussed in Thread: SK-AM62A-LP, SK-AM62-LP

Tool/software:

We want minimal design which runs Linux and we should be able to connect V3Link, and power on module with 5V, and get video through HDMI, and able to connect through Ethernet.

We will copy design from SK-AM62A-LP, but our question is if we remove those parts, can we still run SoC? We are working on this; PROC135E3_SCH.

TPS65988DHRS
TPS62177DQCR
TLV705075YFPT (we will not use CAN)

TPS22902YFPR

TS3DV642RUATQ1 CSI mux (We will not use 2 output, we only connect V3Link, do we need to still use it, can we remove all parts completly, and connect V3Link directly to U18K?

Can you please help about thoose? Thanks...

My next question is LPDDR4 selection help, MT53E2G32D4DE-046 AAT:A, this one written on the BOM is difficult to find, if we use any LPDDR4 which has same Data Bus: 32 bit and 64Gbit than is that will work without any problem?

For example; https://eu.mouser.com/ProductDetail/Kingston/Q6422XM3BDGVK-U?qs=2wMNvWM5ZX5FVfb8Hya%252Byg%3D%3D

If we also change it to 2GB ram version https://eu.mouser.com/ProductDetail/Micron/MT53E1G32D2FW-046-WT-ESC?qs=3Rah4i%252BhyCHzUt4hMcbCww%3D%3D would it work too? What changes we should make?

Thanks...

Helo Betul Aktepe,

Please draw a bloc diagram on the implementation you have.

I suspect it would be easy to verify the block diagram of the equipment you have in mind.

Hi Kallikuppa, thanks for your fast reply, this is block diagram that we want, minimum parts that require system to work. Can we remove other parts, and copy design of SK-AM62-LP?

Also, can you help us how to choose 1GB, 2GB Ram, also for changes, which modification we need to do?

Thanks for your help.

Helo Betul Aktepe,

Thank you.

The blocks you have seems to be Ok.

Make sure the 25M crystal or oscillator is used. 32K is optional.

The bootmode buffers could be optimized.

We are recommending having at the least TPs for JTAG interface.

Sreenivasa
