LMK1D1204: Design review

Guru 11050 points
Part Number: LMK1D1204
Other Parts Discussed in Thread: LMK6D

Tool/software:

Hello,

My customer requested a review from TI for their LMK1D1204 design below.

Please review the circuit design to see if there are any problems.

The output waveform specification of the oscillator is LVDS.

  

Thank you in advance.

  • Hi JH, 
    Why don't we propose customer use LMK6D instead (LVDS output)? Instead of competitor part? 
    If input is an LVDS signal, simply DC couple with a 100Ohm differential termination: 

    On the output side, correct termination is as follows: 

    If DC coupled, just 100Ohm differential termination but if AC coupled, the receiver must be biased internally. 

    Best regards, 

    Vicente
