Part Number: TS5MP645
Is it possible to use the IC for switching LVDS serial lanes running at 1.2Gbps?
In the switches and multiplexers FAQ posting we recommended selecting a signal switch that has a channel bandwidth of 1.5 times the datarate.
For example, a 1.2Gbps signal passing per channel, we would recommend a switch with a bandwidth of 1.8GHz.
The TS5MP645 bandwidth minimum is 1.5 GHz and typically 2 GHz which would meet that requirement.
What is the 1.2Gbps signal used for in your system and why do you need a switch?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Adam hi Thanks for the quick response. Due to the fact the TS5MP645 is available only as 0.4mm pitch BGA I cannot use it for my application. The next candidate is to use HD3SS3415 or HD3SS3412 for the following requirement: 1. Able to switch 4 lanes of MIPI signals running at max bitrate of 1.5Gbps 2. Able to switch LVDS signals with 1.2Gbps 3. In gernerally I wish to employ it for USB3.0, PCIe, HDMI 2.0a, DP 1.4 switching. Q1: Can this IC be good for the above tasks ? Q2: The MIPI standard low power mode defined with low rate (~10Mbps) high amplitude (~ 1.2V) switching - will it support this feature? Q3: Will it be able to switch single ended signals? also in the order of ~10Mbps ? Thanks in advance Oded A
In reply to Oded Avraham:
The HDMI standard specifies TMDS with electrical levels of 2.7 - 3.3V above GND. The HD3SS3415 recommended voltage range is between 0 and 2V. This would work if the voltage level was AC coupled like PCIe, but would be a problem in a DC coupled application.
