Quake Launches Industry’s First Single-chip 11.1 Gb/s Bidirectional CDR

3/18/2003 - Fabless semiconductor company Quake Technologies, Inc. is bringing 10G networks to new levels with the announcement of the availability of the QT1010, the industry’s first single-chip 9.953 to 11.1 Gb/s bidirectional clock and data recovery (CDR) unit. With the flexibility to meet SONET OC192/SDH STM-64, 10 G Ethernet, G.709 and 10 G Fibre Channel requirements, the QT1010 enables XFP-based applications to work seamlessly across all platforms. The QT1010 bidirectional CDR is a protocol agnostic device that delivers industry-leading performance. It passes the most stringent of XFP compliance testing for both datacom and telecom applications. Leveraging the success of Quake’s 10G Ethernet and 10G SONET SerDes products, the single-chip bidirectional CDR demonstrates superior 10G performance at both fiber and XFI interfaces, well exceeding the XFP requirements.

“Quake is leapfrogging a traditional two-chip solution with a single-chip bidirectional CDR,” said Carolyn Raab, VP of marketing, Quake Technologies. “This allows our customers to implement first-generation products with all of the advantages that our advanced architecture brings. The QT1010 will enable the full range of XFP modules with best economics and this will help to drive a real inflection point in 10GE deployment.”

The path to cost effective 10 Gb/s in all networks
For 10 G-based networks to reach broadest deployment, XFP (www.xfpmsa.org ) modules are being specified to enable inexpensive 10 Gb/s client interfaces. Quake is a member of the XFP 10 Gigabit Small Form Factor Pluggable group developing a Multi-Source Agreement for a next-generation optical transceiver. The technology is intended to be flexible enough to support OC192/STM-64, 10 G Fibre Channel, G.709, and 10 G Ethernet, usually with the same module. A key piece of electronics within XFP is the CDR function required in both the transmit and receive directions of the module.

Highly integrated single chip makes XFP possible
The QT1010 bidirectional CDR makes use of Quake’s advanced CDR technology that offers the industry’s best jitter tolerance, jitter transfer and jitter generation performance. It provides the interface between a host 10Gb/s SerDes on the system card and the optical sub-assemblies inside an XFP module. In the transmit direction, the QT1010 compensates for loss and distortion caused by the electrical interface from the host SerDes to the XFP connector. The regenerated signal is provided to the optical transmitter sub-assembly. In the receive direction, the QT1010 performs clock and data recovery and regeneration of the signal from the optical receiver sub-assembly.

Stressed eye and extensive bit error rate testing prove the robustness of the QT1010 over all corners of operating conditions. With very low maximum power consumption and performance to meet the most severe requirements, the QT1010 can be used for any XFP application. Delivered in a 7x7mm BGA, the part occupies a very small footprint, while providing excellent isolation between transmit and receive paths. The advanced architecture of QT1010 includes multiple loopback and test features that dramatically improve the debug and manufacturability costs in both XFP modules and on the system card.

QT1010 includes an integrated limiting amplifier that offers excellent input sensitivity to operate with a broad range of input signals on both fiber and client sides. Its XFI performance exceeds the XFP requirements and is fully interoperable with downstream SerDes such as Quake’s QT2021, 10GE to XAUI SerDes.

Pricing and availability
Samples of the QT1010 are available priced at US $250 each for small quantities. Full production of the QT1010 is planned for mid-2003.

A complete evaluation kit and technical documentation are available upon request.
