DP83869HM: SNLS614B – SEPTEMBER 2018 – REVISED DECEMBER 2022

Part Number: DP83869HM

Hello Team,

we are a little bit confused about the changes compared to SNLS614A.

In 100M Media Converter Mode (9.4.8.6) was added:

• Write 0x000E to register 18h // Mux LED_1 to function as RX_ER, but 0x000E is the value for LED_0 !!??

But we has configured LED_1 as 'link OK'.

LED_1 and LED_2 are strapped to 1and Link Loss Pass Thru is enabled (RX_CLK strapped to 0) as shown in table 9-15, OPMODE(0) and OPMODE(2) are strapped to 1 (as shown in table 9-9: 100Base-T to 100Base-FX mode)

What is the background to write the function RX_ER to LED_1? Can we use LED_1 further as indication for a link at the FX-side?

Also the PHYIDR2 Register (Table 9-22) was modified to A0F3h (REVISION_NUM=3h), but in FX_PHYID2 Register (Table 9-89) the revision number stays at REVISION_NUM_FIBER=1h. Is that correct?

Best regards,

Dieter
