LVDS Bridge

There are only 1:4 devices like the SN65LVDS104.

Thanks Josh, Whether i can connect two lvds display using above SN65LVCP22? what i need to do SEL1/0, EN0/1 pins.

Hello Sathiyan.

If using the device in a 1:2 Splitter configuration, then use the following:

If using Input 0, then make SEL0 and SEL1 = 0

If using Input 1, then make SEL0 and SEL1 = 1

Function table and block diagram can be found on page 2 in the datasheet. Hope this helps.

Josh

SN65LVCP22 is used in the LVDS Splitter, it will work?

Hello Sathiyan,

That's correct. In this mode the device is essentially a fanout.

fanout means need buffer?

Hello Sathiyan,

No, a fanout means you are distributing the input signal to other outputs. The SN65LVCP22 is a buffer since it's a differential to differential device.

Everything are LVDS still need Noise Margin Analysis,  

iMX6 - LVDS Splitter - O/P1 LVDS Display

                                  -O/P2 LVDS to RGB Converter

Hello Sathiyan,

Unfortunately, we don't have any noise margin analysis for any of our LVDS devices.

this looks good?

Hello Sathiyan,

The schematic looks good.

For the unused differential inputs [Input 0] I would recommend to tie the "+" input to VCC and the "-" input to GND.

Josh

Thanks Joshua, Can i use 0 ohm or 100 ohm or 10K ohm for the unused differential inputs.

Hello Sathiyan,

A 10 kΩ will work fine.

Thanks Joshua, TI having any LVDS Isolator Solutions?, I am in need isolate two LVDS Chips.

Hello Sathiyan,

Yes we do have a few isolated LVDS buffers. Take a look below.

Just note these products don't fall under my team so if you need additional information on isolated LVDS buffers, then I can redirect your question to the isolation team.

SN65LVCP22, what min decaps?

Hello Sathiyan,

Use high-frequency, ceramic, 0.1-µF and 0.01-µF capacitors in parallel at the power supply pin with the smallest value capacitor closest to the device supply pin.

Josh

Thanks Josh, SN65LVCP22 will support 4K and 1080p Video, I am using conversion after lvds spillter, to connect to monitor, DS25CP152TSQ/NOPB is better part compare to SN65LVCP22? Because i little bit varied about transmitted speed.

SN65LVCP22 is Read and Drive at 1x2 Splitter Mode.

Hello Sathiyan,

I'm not sure if I understand your question.

Josh

It is active device?

Hello Sathiyan,

Are you asking if the SN65LVCP22 is active as in purchasable? Then the answer is yes.

Regards,

Josh

No, it is pass through or read and drive?

Hello Sathiyan,

The device is pass through only
