GuideTech and Roos Instruments Target Low-Cost Clock Test with Integrated CTIA and Cassini Open Architecture ATE Platform; GT4000/Cassini Integrated System to Be Displayed at SEMICON West, Booth 8519, San Francisco, July 11-13.

SUNNYVALE, Calif. -- GuideTech, provider of high-throughput precision timing solutions, and Roos Instruments, provider of precision RF test systems, today announced GuideTech's CTIA-based jitter and timing test systems are being integrated into Roos Instruments' modular Cassini tester platform. The GuideTech Femto 2000 and GT4000 CTIA Continuous Timing Interval Analyzer systems extend test capabilities of the very low-cost Cassini test system to address the cost-sensitive clock device market by enabling test of critical clock AC timing parameters at throughput speeds unmatched in any other production test environment.

"Cassini was designed to scale from very low cost to very high performance RF capability with an extensible architecture that easily accepts third-party instruments for added capability in other applications such as clock devices," stated Mark Roos, Roos Instruments CEO. "Though perfect as a dedicated low-cost clock test solution, a company with other RF devices could eventually add our other RF instruments and have a common platform for several device test applications."

"Many clock companies face the dilemma of deciding whether or not to replace hundreds of 30-year-old, often home-made test systems with more costly high-performance testers in order to meet the growing demands of customers who now require guaranteed clock performance at final test, rather than merely 'guaranteed-by-design,'" stated Tammy Lee McClure, GuideTech VP Marketing. "The combination of millisecond throughput and picosecond accuracy of critical AC timing measurements make GuideTech CTIA instruments the perfect add to the Roos' low-cost, open architecture Cassini platform. Compared to slower oscilloscopes and spectrum analyzers we feel that the timing is perfect for GuideTech's unique CTIA technology to save tremendous costs for the industry's clock manufacturers."

Key capabilities driving the rapid adoption of the GT4000/Cassini integrated solution include:

--Open architecture: Buy what you need for today and upgrade in the field to get what you need for tomorrow

--Benchtop RF accuracy and correlation with production test time

--Modular support model: Faster time to repair and lower maintenance costs

--Graphical test plan development and debug environment simplifies development cycle

--Guaranteed quality assurance for clock jitter, rise/fall time, PLL lock time, Spread Spectrum Modulation, Phase Noise and differential skew and voltage crossing specifications

About GuideTech

GuideTech is the leading innovator in high-performance CTIA-based timing measurement instruments, providing semiconductor manufacturers with the solution they need to minimize timing-related component failure and to dramatically reduce production test costs through test-time reduction and extended ATE lifecycles. Based on patented Continuous Time Interval Analyzer (CTIA) technology, the company's Femto 2000 and GT4000 families of multi-channel timing test systems and accompanying Datacom Analysis software substantially improve test throughput via fast measurement rates, far greater measurement and analysis accuracy, and the ability to handle asynchronous or non-deterministic signals without external arming on up to 32 or 64 channels. These capabilities, which are strongly linked to GuideTech's unique CTIA technology, enable critical, high-speed, functional, timing and jitter test coverage for PLLs and multi-gigabit serial interfaces such as PCI Express and Serial ATA, in milliseconds, in parallel, and in production. Headquartered in Sunnyvale, CA, the company is the first to deliver cost-effective, advanced timing measurement solutions that easily integrate onto any ATE platform.
