DS90UB953-Q1: Power Consumption of Device with low PDB pin & Application notes

Part Number: DS90UB953-Q1

Hi,

Below is the request and questions from my customer.

I need the following application notes mentioned in the datasheet:

1. How to Design a FPD-Link III System Using DS90UB953 and DS90UB954 (SNLA267)

2. Power-over-Coax Design Guidelines for DS90UB953-Q1 (SNLA272)

3. Schematic and Layout Checklist for DS90UB953-Q1 (SNLA271)

I couldn’t find them in your website. If there are any more application notes, please forward. (I don’t remember asking for these application notes earlier)

Queries:

I also want to know the power consumption of the device if “PDB” Power-Down pin is pulled low.

Is there any way to reduce the device power consumption without pulling this PDB pin low. (using I2C commands)

Can you please help on this?

Regards,

Aniket,
The POC design guidelines for DS90UB953 app note is available on ti.com in the 953 product folder: www.ti.com/.../technicaldocuments
The other two app notes SNLA267 and SNLA271 are going through updates and will be released on the web when they're completed.

Hello,

the power consumption of the 953 while PDB is low is approx. 100 mW.
there is no way than you can reduce the power consumption using I2C commands.
