Review schematics & PCB Artwork using ADSP-SC589KBCZ-4

Moving to ADSP-SC5xx/ADSP-215xx community

Dear Santha, 

When do you review my schematics and PCB?

Hi,

We have reviewed following portion in your schematic and added our comments in excel sheet,
1.    ADSP-SC589 Processor
2.    DDR3
3.    Power section
4.    Flash
5.    EEPROM
6.    USB
7.    SD Card
8.    Boot switch and Debug section
9.    Clock and RESET section
We could not find Ethernet datasheet from website. Soo we are not reviewing that section.

Dear Anand,

Thanks for your answer.

I have questions your comments in excel sheet below this.

1. U4/U5 VREFDQ,VREFCA

   Does that mean that parts(Decaps) should be placed close to each signals(VREFDQ/VREFCA)?

 2. USB0 Signals

   I don't understand your comments.

   Please explain in detail.

  (USB0 will be used to read and play MP3 files in external USB memory) 

And, To send the datasheet for Ethernet to your email , Please inform me your email address.

Thank you.

Best Regards,

Inho Jeon

Hi,

For U4/U5 VREFDQ,VREFCA Decaps connection, please refer the SC589 schematic from the below link,

www.analog.com/.../EVAL-ADSP-SC589.html

We couldn’t see, where the USB0 signals are connected in your schematic.

Please share your Ethernet data sheet to processor.support@analog.com mail.

Anand Selvaraj.

Dear Anand,

Thank you for reply.

I'll change same ethernet IC that is use for ADSP-SC589 EZ-Board.

So, I don't send ethernet IC(Marvell) datasheet.

And,  I have a question your "ADSP-SC589 EZ-Board Schematic". 

Is it need to "NFE61PT472C1H9L" on VDD_ADC & HADC0_VREFP ?

I think that part is over specification.

So, inform me replacement part of that.

Thank you.

Best Regards,

Inho Jeon   

Dear Anand,

I attach schematic that modified Ethernet part same as ADSP-SC589 EZ-Board & ESD suppressor SpecSheet. 

I add ESD suppressors(U86,U87) for RJ45 Jack(J13).

Is it right ESD suppressor for good working well ADSP-SC589?

Thank you.

Best Regards,

Inho Jeon

Hi,

We didn’t implement any ESD protector in our Ethernet design.

The Ethernet Transceiver DP83867IR has ESD protection.

Please refer the DP83867IR datasheet Page no: 14 for ESD details,

Dear Anand,

I have a question your "ADSP-SC589 EZ-Board Schematic". 

If not use HADC and TMU,  then "NFE61PT472C1H9L" is not use, is that right?

Thank you.

Best Regards,

Inho Jeon   

Hi Inho Jeon,

Yes, you are correct. No need for "NFE61PT472C1H9L" device, If you are not going to use HADC and TMU in your design.

Anand Selvaraj.
