Part Number: LMK03318
Dear, Support Team.My customer is going to use LMK03318 with LDVS input and output.
Input frequency: 100 MHzInput waveform: DC-LVDS (datasheet Fig 49)Output frequency: 100 MHzOutput setting: AC-LVDS
There is AC - LVDS Output Characteristics on page 23 of the data sheet.Can the customer use the DC-LVDS to AC-LVDS setting and DC-LVDS output?
Best Regards,Hiroaki Yuyama
The AC-LVDS driver has low output common mode voltage (Vos range = 150 to 350 mV) and cannot tolerate a external biasing from the receiver, which is why the AC coupling is recommended between the AC-LVDS driver and a LVDS receiver with input biasing. If the LVDS receiver can accept the low Vos range and has no internal biasing, then it is possible to use DC coupling between the driver and receiver, and terminate with 100-ohms differential across the receiver inputs.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
