Sunnyvale, CA - February 1, 2000 - Newnex Technology Corp. announced today that the USB connector systems it manufactures  meet and exceed the requirements specified in the newly released USB ECN (Engineering Change Notice) for USB specification 1.1, which is the most current USB standard.  This ECN addresses those areas where USB1.1 was not clear or silent for testing USB cables and connectors. The changes are:

• Add the attenuation limit (<5.8 dB at 4000 MHz)
• Specify the common mode impedance (Zcm) must be 30 Ohms
• Clarify one way cable delay is 5.2 ns/m
• Tighten cable skew to 100 ps
• Specify DC resistance from plug shell to plug shell < 0.6 Ohms for EMI reduction

Testing data shown, by incorporating the above changes as an ECN to USB 1.1 specification, Newnex connectors systems will also support USB2.0 signaling rates. USB2.0 is the faster version of USB1.1, which is capable to transfer data at 480 Mbps or higher rate and fully forward and backward compatible to USB.1.1. USB2.0 has been promoted by Compaq, HP, Intel, Lucent, Microsoft, NEC and Philips. There are about five hundred companies worldwide participating the developing of USB2.0 specification and products. Newnex USB connector systems include the following:

• Single Series A and Series B receptacles in either right angle or vertical configuration
• Stacked Series A receptacle in right angle configuration
• Series A to B cable assemblies with standard lengths as 1, 2, 3 and 5 meters.
• Series A and to custom end cable assemblies in various lengths.
