Tool/software:
Hi team,
Could you please help to answer inqueries below?
- Could you let me know the maximum value of the T5 Fast Link Pulse transmission delay post power up on 7.6 Timing Requirements, Power-Up Timing?
- Regarding MDIO I/F, is it allowed to stop providing the clock if MDIO access is not used?
- If MDC clock is stopped and then accecc by MDIO again, is it possible to access that if the MDC clock is input?
Also, please let me know if any limitation from MDC clock input to MDIO access. - In the table 0x0025 MLEDCRのBIT[1:0] > MLED Route to LED_0, the default is described as 0b00=MLED routed to COL.
Isn't it 0b11=MLED routed to LED_0? - In tha table 8-46.0x003E PTPPSEL BIT[6:4],[2:0], the default is shown as 0b000. However, it is not shown as 0b000 on the FUNCTION.
Is it okay to leave it as 0b000 when IEEE1588 is not used? - In the table 8-48.0x0040 Fiber Far-End Fault Generation/Detection Force, my customer doesn't get what this is.
Could you let me know the datahseet page which explain this functionality? - Table 8-49.0x0042 TXCPSR is only needed when using MII and it is not needed for RGMII, correct?
- Regarding Table 8-51.0x0106 DFCR1, should it be modified when short cable is used? Or, is it okay to leave it default?
- Regarding Table 8-64.0x0170 CDSCR, is it okay to leave it as default when the TDR is not used?
- Regarding Table 8-66.0x0173 CDSCT3, is it needed to modify when the long cable is used?
- Regarding Table 8-67.0x0177 CDSCT4, is it needed to modify when the short cable is used?
- Regarding Table 8-91.0x0456 GENCFG BIT[3], it is mentioned as Note:IPGs <200ns should only be used when operating with a MII MAC IF configuration.”
Does this mean Min IPG Enable should be set from 0b1 to 0b0 if the I/F except for MII is used? - In Table 8-94.0x0462 IOCTRL1 BIT[10:8]RX_D3/GPIO_3Control FUNCTION, it is shown as 0b000:Normal operation.
Does normal operation operate in RX_D3? - In Table 8-94.0x0462 IOCTRL1 BIT[10:8]RX_D3/GPIO_3Control FUNCTION, it is shown as 0b000:Normal operation.
Does normal operation operate in COL? - In 9.2.2.2.4 MDI Layout Guidelines, there's description regarding RJ45 connection. Could you provide the guideline fro 100BASE-FX application as well?
- What is the recommended spec of the AVD supply ferrite bead on Figure 9-2?
- What is the recommended spec o VDDIO/AVD ferrite bead on Figure 10-1?
- Could you let me know the maximum current and power comsumptions on Table 10-1?
Also, which pin sonsumes the current specified on MAGNETIC SUPPLY in Table 10-1?
Best regards,
Kazuki Itoh
