DS100DF410: Can each channel operate at independant rates (1.25Gbps or 10.3125Gbps)

Posted on behalf of a community member:

Question: Is the DS100DF410 capable of running at 10.3125Gbps or 1.25Gbps independantly on any channel? In other words, can some of the channels run at 1.25Gbps and other channels simultaneously run at 10.3125Gbps?

    Answer: Yes, each channel in the DS100DF410 has an independant voltage controlled oscillator (VCO), which means that each channel can independantly lock to a different data rate, for example, 1.25Gbps or 10.3125Gbps.

    Hi,

    I'm using DS100DF410 in my design for 10G Ethernet applications. kindly let us know that  DS100DF410 lanes can be configured  to work in full duplex mode(can simultaneously configured as transmit & receive channels).

    The DS100DF410 is a four-channel uni-directional retimer, meaning all four channels point in the same direction (left-to-right if you're looking at the device from the top with pin 1 in the top-left corner). You can certainly use this device for a bi-directional application, or as you say full-duplex. Since each channel will independantly lock, you could use two channels as "receive" and two channels as "transmit."

    It might be easier for you from a layout perspective to use one of our bi-directional retimers, like the DS110DF111. This is a two channel bi-directional retimer in a 4mm x 4mm package and might be better for your application.

    Regards,
