SN55LVDS31: SN55LVDS31 compared to SN65LVDS31

Part Number: SN55LVDS31
Other Parts Discussed in Thread: SN65LVDS31, , SN65LVDS32

Dear，

 Does SN55LVDS31 work with SN65LVDS32? Or is SN65LVDS31 with SN65LVDS32 better? 

From the data sheet, except the operating temperature is different between SN55LVDS31 and SN65LVDS31, the Ioff (max) current is also different. Does Ioff effect the signal decrease with long cable usage? 

If SN55LVDS31+SN65LVDS32, what is the signal integrity compared to SN65LVDS31+SN65LVDS32?

As SN55LVDS31 has wider temperature range,  does the transmitter SN55LVDS31 work beyond the receiver SN65LVDS32 temperature range?

For example,SN55LVDS31 works at -20degree and SN65LVDS32 works at 25degree? 

Best regards

Kailyn

    Hi Kailyn,

    Yes, SN55LVDS31 will work with the SN65LVDS32. Keep in mind the SN55LVDS31 is a space qualified device. If you don't need space qualifications you should just use the SN65LVDS31. Ioff does not effect the signal, and the signal integrity is similar. You can reference the datasheets for the temperature range for each device. 

    Regards,
