ADDI7015 : TCLK

Hello,

I have some questions about the ADDI7015.

Q1:

The AFE has the LVDS output of four channels.

TCLK of the LVDS output separates for the A/C channel and for the B/D channel.

I want to use only either of TCLKx_AC or TCLKxBD.

CLI of AFE is used with 32MHz.

For instance, only the TCLKx_AC is used to transmit the data of A, B, C, and D channel.

In a word, FPGA receives the data of B and D channel with the TCLKx_AC clock.

Is it possible?

Q2:

I not use neither XVx nor the Hx signal.

I will non connect these terminals.

Is it all right?

Best Regards,

Mr.K

  • Hello,

    Q1 reply:

    Our recommendation is to use the channel specific TCLK (for example TCLKx_AC for DOUTx_A/C, and TCLKx_BD for DOUTx_B/D). However, at low data rates where the data eye is larger, this could be possible, but it is not guaranteed.

    Q2 reply:

    Yes, your understanding is correct. For unused HCLKs or XVs, please keep the pins unconnected.
