May TI have part can competitor with QLx4600-S30 or ISL36111?

Hi Chen,

The DS100BR111 is much closer to the ISL3611.  The DS125BR401A is an 8-channel device, the DS100BR111 is just a two channel device often used in cabling applications.  For applications with link or equalization training, like 10G-KR Ethernet we recommend using the DS125BR111 linear equalizer.

Hi Lee

My customer want use in VR cable, may you have any other suggestion or what something we need to notice?

Hi Bogey,

You will need to determine how much loss in dB is introduced by the cable. In addition, it will be helpful if we know what protocol is running. For example, if you are using a protocol like PCIe Gen-3, SAS-3, or 10G-KR, we will typically recommend the DS125BR111 instead of the DS100BR111 in order to support link-training through the DS125BR111's linear equalizer.

Hi Michael

Sorry for i have some confuse, from DS100BR111 datasheet also have link-training...

I it seems DS125BR111 Just speed higher than DS100BR111. am i right?

Hi Michael
The VR cable use for DP single and just know use 32AWG 5 meter length.
Due to customer just need uni-direction, so we have promote ds100br210 to customer(is this part suit DP protocol?)
If TI TYPE C have cable solution suit 5M and can run 10G speed.(for customer concern is TYPE Cmay run usb3.0/DP/USB2.0 signal or Alternate protocol) so customer want know if TI have repeater or retimer suit in type C application?
The customer have mention TUSB546, but i can find in web. may we check if this part related information?

Hi Bogey,

The DS100BR111 can support applications with link-training, but it requires more tuning than the DS125BR111, as the DS125BR111 is an advanced linear repeater. Due to the more linear behavior of the DS125BR111, this repeater can help maintain pre-cursor and post-cursor characteristics embedded within the signal that it receives as the signal passes through the device. The DS100BR111 can also do this too, but it requires much more careful tuning, as the less linear EQ in the DS100BR111 does not preserve the pre-cursor and post-cursor characteristics as well. Aside from this difference, you are also correct that the DS125BR111 supports a higher data rate than the DS100BR111.

We have not tested the DS100BR210 for DP applications, since our products mainly are applied in the enterprise application space. I suspect that the DS100BR210 should work fine, since it is a simple repeater and does not perform any type of digital processing on the signal.

For consumer applications such as USB Type C, I would advise posting your question in the Consumer & Computing Interface forum, where they support the TUSB products and can give you more information about whether they have a suitable product for your needs.

Michael
