SN65LVCP114: sn65lvcp114 application

SN65LVCP114: 10GBASE-KR--SFI Protocol conversion

Part Number: SN65LVCP114
Other Parts Discussed in Thread: DS100KR401

Hi

Ethernet switching IC reaches SN65LVCP114 MUX IC through the backplane, the full high-speed signal protocol is 10GBASE-KR,

After switching SN65LVCP114 MUXVIC switch, the signal protocol required to reach the SFP optical port is SFI.

Does SN65LVCP114 MUX IC support this protocol switch?

SFP--SN65LVCP114-Backplane-PHY, the whole path is about 18inch(10gbase-kr),

Can the driver capability of SN65LVCP114 be reached at such a speed?

thanks！

    Hi Neal,

    Suggestion is to consider DS100KR401. I recommend this part is mainly targeted for KR applications further you can use IBIS-AMI model of this device to do system simulation using your media loss profile.

    Hi

    We're asking the MUX, the IC that has the ability to switch channels, why does it recommend Repeater?

    1. Does SN65LVCP114 support 10GBASE-KR protocol to SFI protocol?

    2. SFP--SN65LVCP114-Backplane-PHY, the whole path is about 18inch(10gbase-kr),Can the driver capability of SN65LVCP114 be reached at such a speed?

    Thanks!

    Hi Neal,

    I missed the switching function feature. Yes you can use LVCP1414 as well since it is a linear redriver and it is protocol agnostic. Suggestion it to use s-parameter model to do system simulation to check on 18-inches backplane eye opening.
