Data transmission accuracy requires sending and receiving clean, error-free data. Jitter is caused by many factors including cross-talk noise, line interface/signal distortion, or even an imperfect timing recovery circuit. At every connection point (node) in a WAN environment, equipment and peripheral devices can cause new errors to be introduced into transmitted data. For precise data transmission, jitter must be reduced.

Exar has a full line of single, and multi-channel jitter attenuator solutions that match, or outperform, other methods, and are much easier to deploy at a lower cost. The XRT71D00, the industry's first jitter attenuator, is a fully integrated single-chip device for DS3/E3 applications. Complementing this device are the XRT71D03 (three-channel), and XRT73D04 (four-channel) parts, which like the XRT71D00, are designed to attenuate the jitter from the incoming clock and data signals. The parts are designed for seamless integration with EXAR's Line Interface Units (LIUs), and access control products enabling designers to implement a complete solution from a single source.

The XRT71D00, XRT71D03, and XRT71D04 meet the European Telecommunications Standards Institute (ETSI), technical committee draft standards TBR-24 for digital structured and unstructured leased lines. The Bellcore GR-499, and GR-253, require that terminal equipment, which derives its timing from the received signal at the input port, must not exceed specified output jitter levels. All three devices are compliant with the ANSI T1.105.03b 1997, and ITU G.751, G.752, G.755 standards.
