TLK10232: TLK10232 SFP+ MODULE SUPPORT.

Part Number: TLK10232

Hello,

I am using TLK10232 in one of my project and planning to connect FTLX1475D3BTL SFP+ module on 10G base KR mode.

Will TLK10232 support FTLX1475D3BTL SFP+ module on KR mode?

Thank you.

Regards,

Amarnath G

    Hi Amarnath,

    Yes, the TLK10232 will support that module on KR mode.

    The TLK10232 was characterized for 10GBASE-KR, basically the main features for this mode is the Link Training and the Auto-Negotiation, that are disabled when the device is going to interface with SFP+ optical modules. If the device is going to interface with optical modules, the SerDes settings should be adjusted. If you see errors, please try different values for HS_SERDES_CONTROL_2 & HS_SERDES_CONTROL_3, performing a BER test to get the best combination of values according the characteristics of the system (AC losses, length of traces/cables, etc.)

    Focus first on:

    HS_EQPRE

    HS_ENTRACK

    HS_CDRMULT

    HS_CDRTHR

    HS_PEAK_DISABLE

    HS_HCDRMODE

    Since the link training is disabled, the tuning is manually, hence, for every combination of values you have to monitor the bit error counter in HS_ERROR_COUNTER, and select the error free zone of values.

    Regards,
    I.K.
