DP83640: Looking at replacing the PHY device inside the TMS570 PN: TMS5704357BZWTQQ1 to a PTP compatible drop in replacement.

Jeff Colwell

Part Number: DP83640

Tool/software:

Please help identify a Automotive grade PHY device that is drop in compatible with the TMS570, PN: TMS5704357BZWTQQ1, and uses PTP(can't be interrupt based).

Hi Jeff,

If PTP is strictly required, DP83640 would be suitable if using standard ethernet. We have automotive grade devices with PTP, but they are -T1 devices; DP83TC817-Q1 and DP83TG721-Q1.

Sincerely,

Gerome

- T1, please elaborate?

Hello,

These are Single Pair Ethernet devices, which are not the same as standard Ethernet PHYs such as DP83640, or our more modern portfolio such as DP8382x and DP8386x.

Sincerely,

Gerome

Is it possible to get register maps for both DP83TC817-Q1 and DP83TG721-Q1? We checked the datasheet and did not see register maps for either devices.
