TLK10232: Communication standard

Yuta Nishie

Part Number: TLK10232

Hi,

I have any questions.

1. I think that 10GBASE-KR and 1GBASE-KX communication standards are used with Backplane.

Can TLK10232 be used in combination with an SFP module?

2. I cannnot find the 10G PHY in TI HP's "Products".

Is it possible to use TLK10232 as a 10G or 1G PHY?

Best Regards,

Nishie

    Hi,

    The TLK can indeed be used used to interface with SFP modules.  Each channel of the TLK10232 can be used to convert between XAUI (on the low speed port) and
    10GBASE-R signaling (on the high speed port). The high speed side of the device meets the requirements of the 10GBASE-KR physical layer standard for 10 Gbps data transmission over a PCB backplane. The device can also be used for optical physical layers (like 10GBASE-SR or 10GBASE-LR) by interfacing to optical modules requiring SFI or XFI electrical signaling. For optical use cases, KR-specific features like Clause 73 auto-negotiation and link training should be disabled.

    The TLK10232 is effectively a 10G XAUI to KR PHY SerDes, as it implements both PCS and PMA functions per IEEE.

    Hi Rodrigo Natal,

    Thank you for your reply.

    You said "The TLK10232 is effectively a 10G XAUI to KR PHY SerDes", but datasheet P9, Table 2-3 descript 1G-KX (ST = 1, MODE_SEL pin, Register 1E.0001 bit 10 = 00).

    Is it not possible to use it in 1G?

    Best Regards,

    Nishie

    Sorry, I did not mean to confuse you here. Yes, TLK10232 also supports 1G Ethernet rate, as well as additional data rates in general purpose SerDes mode.

    Thanks,
