TMUXHS4412: TMUXHS4412 Data Rate Issue

Part Number: TMUXHS4412
Other Parts Discussed in Thread: TMUXHS4212

Dear Sir:

TMUXHS4412 Data Rate Issue

TMUXHS4412 4-Channel 20 Gbps Differential.

1. It means the each channel Differential signal can Data rate support up to 20 Gbps.

Is it correct?

2. or 4-Channel 20 Gbps Differential. Each channel Differential signal can Data rate support up to 5 Gbps only? 20 Gbps/4-Channel = 5 Gbps/channel.

Please check to reply us asap.

Thanks a lot.

Best regards,

Vincent

  • 1 is correct , each channel is 20Gbps.

  • Dear Sir:

    1.Regarding the TMUXHS4412 Data rate

    1-1 each channel Differential is 20Gbps.

    *D0P / D0N: Differential Data rate 20Gbps.

    *D1P / D1N: Differential Data rate 20Gbps.

    *D2P / D2N: Differential Data rate 20Gbps.

    *D3P / D3N: Differential Data rate 20Gbps.

    Is it correct?

    1-2. Use 4-Channel, the total Data rate = 4* 20Gbps = 80 Gbps

    Is it correct?

    1-3 If use the only one channel.

    D0P / D0N: Is Data rate still 20Gbps(max)?

    or Can Data rate be up to 80Gbps(max) because use one channel ( the others 3ch no use)?

     

    2. Regarding the TMUXHS4212 Data rate

    2-channel 16-Gbps 2:1/1:2 differential mux/demux

    2-1 each channel Differential is 16Gbps. 

    *A0P / A0N: Differential Data rate 16Gbps.

    *A1P / A1N: Differential Data rate 16Gbps.

    Is it correct?

    2-2. Use 2-Channel, the total Data rate = 4* 16Gbps = 32 Gbps

    Is it correct?

    2-3 If use the only one channel.

    A0P / A0N: Is Data rate still 16Gbps(max)?

    or Can Data rate be up to 32Gbps(max) because use one channel ( the other one no use)?

    2-4 B0P/B0N description: connector side.

    It doesn’t understand why B0P/B0N has the description connector side

    B0P/B0N can connect to connector side only? C0P/C0N cannot?

    Please check to reply us asap.

    Thanks a lot.

  • max data rate of each channel is 20Gbps, no matter one channel or 4 channels are used.

  • 1: correct.

    2; there is no difference between B0P/N, C0P/N, they can connect either side

  • Dear Sir:

    Regarding the TMUXHS4412 application.

    1.Does TMUXHS4412 support the Ethernet Interfaces ( 10GBASE-T 4-pair UTP 10Gbps)?

    2. Does TMUXHS4412 support the UFS2.1 & 3.1 Interface.( 4channel )?

    UFS 3.1:

    *VDIFF High-speed signal pins differential voltage(VPP) : 280~620mV

    *VCM: High speed signal pins common mode voltage(V) : 160~310mV

    UFS 2.1:

    *VDIFF High-speed signal pins differential voltage(VPP) : 280~500mV

    *VCM: High speed signal pins common mode voltage(V) : 160~260mV

    UFS Ver

    Bandwidth per lane (Differential Signal)

    2.1 HS

    5.8Gbps

    3.1 HS L

    11.6Gbps

    Please check to reply it asap.

    Thanks a lot.

  • Vincent:

         1: should work, can you send VDIFF and Vcm as well?

        2; will work.

    Regards

    Brian

  • Dear Sir:

    For UFS2.1 & 3.1 Interface.( 4channel ) application

    Use TMUXHS4212(16Gbps/2ch) * 2pcs IC to support the UFS2.1 & 3.1 Interface.( 4channel ).

    It will work. Is it correct?

    Please check to reply it asap.

    Thanks

    B.R

    Vincent

  • you mean one 4212 support UFS2.1 and another support UFS3.1? it should work.

    Regards

    brian

  • Dear Sir:

    Please check the following block diagram.

    Use TMUXHS4212(16Gbps/2ch) * 2pcs IC to support the UFS2.1 & 3.1 Interface.( 4channel ).

    It will work. Is it correct?

    Please check to reply us asap.

    Thanks
