Quake crafts 10Gb transceiver in SiGe

Quake Technologies Inc. has unveiled a serial transceiver that targets 10.3Gbps IEEE 802.3ae Ethernet and 10.57Gbps Fibre Channel system designs. Quake said the QT2021 SiGe transceiver increases the functionality and decreases the power consumption of its initial 10GbE offering, the QT2020 serdes, released a year ago.

The QT2021 delivers jitter <10ps peak to peak, roughly a 50 percent improvement over the QT2020, said Carolyn Raab, VP of marketing at Quake Technologies. The 2021 also sports built-in set-test features and pattern generator/checkers for jitter, Ethernet, and PRBS.

"In the end, we all have to be cheap," Raab said. "The question is: Do you offer a system solution?" By integrating the generators, checkers and test features, Raab said that Quake is adding those system functions.

Quake also focused its efforts on dropping power consumption in its new serdes offering. The result is a transceiver that delivers 1.9W power dissipation, Raab said.

Data bus is XAUI

The QT2021 converts a 10Gbps serial stream into four 3.125Gb or 3/1875 serial lanes via the IEEE XAUI data bus. The device can operate on a fiber-optic module such as XENPAK, XPAK, or X2, or directly on a line card with XFP modules.

Like the earlier QT2020, the new transceiver features adjustable XAUI and 10Gbps fiber-side output levels. Additionally, the transceiver's clock-and-data recovery unit requires no external clocks, with both fiber-side and Xaui-side CDRs needing only signals at normal data input channels.

The QT2021 comes in either a 19-by-19mm or 15-by-15mm package. Priced at $500 each in 1,000-unit quantities, the transceiver is sampling now. Full production is planned for Q3 of 2003, the company said.
