Chip Pushes Twisted-Pair Copper To 10 Gbits: Page 2 of 2

The result, according to Raghaven, is a chip that achieves a great deal in a standard technology. The front-end amplifier sends the signal from the copper to a high-linearity A/D converter operating "in the range of 1 Gsample/s." That data, in turn, is multiplexed into a bank of four DSP data paths responsible for decoding and FEC computation. Of course, there is a complementary transmit path.

Vativ is betting that availability of the chip in advance of a 10-Gbit Ethernet standard, along with the chip's demonstrated compatibility with CAT5e-6 cable and RJ-45 connectors, will give the company an early beachhead in the data center, where proprietary 10-Gbit connections with a range of less than 15 meters or so make economic sense. The company is working with partners to provide the chip in modules that could drop into existing Xenpac slots without mechanical or software changes, giving data center managers an alternative to short-haul fiber at a fraction of the total cost.
