SN65LVDS4: alternative or 1.8V LVDS, 80MHz output solution

Prodigy 10 points

Part Number: SN65LVDS4
Other Parts Discussed in Thread: SN65LVDS2, SN74AUC1G125, TLV713P

Could you tell me an alternative device or circuit for LVDS receiver SN65LVDS4 operating at 1.8V single power supply?
- Input: LVDS differential signal at 70 to 80 MHz.
- Output: 1.8 V high level.
- Operation power: 1.8V single power supply. The printed circuit board has 3.3 V power supply, but I don't want to use it if possible because it is noisy.
- A one-chip configuration is preferred. However, it is permissible to use multiple ICs or increase peripheral parts.

    Hi,


    Your issue is being assigned to the appropriate engineer. Due to the US Holiday there may be a delay in response to your post. We apologize for any inconvenience.

    This device is the only 1.8 V receiver in the portfolio.

    You can use the SN65LVDS2 at 3.3 V, or at 2.5 V with a small LDO like the TLV713P. If the receiving device needs a 1.8 V signal, translate it down with any buffer with an overvoltage-tolerant input, e.g., SN74AUC1G125.

    Thank you very much.
    If you don't use 3.3 V, you can't make it happen. I want to minimize the effect of noise mixed at 3.3 V power supply as much as possible.
    Thank you for giving me an example of devices. I was helpful because I was not sure which one to choose.  I will try the circuit of your idea.

    Regards,
