Other Parts Discussed in Thread: HD3SS3415, HD3SS3412
Hi
Is it possible to use the IC for switching LVDS serial lanes running at 1.2Gbps?
Thanks

Oded,
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?
Thank you,
Adam
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

Hi Oded,
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.
