JEDEC Clock Reference Board For PC2700 (DDR333) DIMM

Thursday, August 23, 2001 CST Inc,DDRtester.com today announced initiative for the new “PC2700/DDR333-DIMM Clock Reference Board”. This new clock reference board will be designed in co-operation of Integrated Circuit Systems and IBM Micro Electronics . CST, Inc. will handle manufacturing and distribution to the industry.

This “Clock Reference Board”, endorsed by JEDEC, is designed to serve as a test vehicle especially for module designers and module manufacturers (purpose is to “fine tune” memory module assembly during validation), the reference board is also targeted as a qualification vehicle for PC system producers.

The Clock reference board consists of a clock generator which generate several buffered clock output signals. The clock signals are routed to the DDR-DIMM module test socket and to the “Reference Net Circuit”.

An Oscilloscope is used for the waveform measurement at the DDR-SDRAM. These measured waveforms are then compared against measurement taken from the “Reference Net circuit” for time delays and skew.

CST Inc will be building all the Clock Reference Boards in one batch to ensure consistency. A “Golden” Board will be maintained to support future builds.

CST had previously taken up the task of manufacturing and distributing the PC100/PC133 DIMM clock reference board and the PC2100 DDR266 DIMM clock reference board..

Founded in 1983, CST designs, manufactures, markets and support computer memory test software and hardware. CST pioneered the first low cost SIMM tester for computers in 1985. Since then, CST testers have become the standard for computer manufacturing industry, holding more than 70% of the market in memory module testers for computer manufacturers and third party memory module manufacturers. With its product lines of memory module tester and handler, CST is equipped to handle all aspects of memory module testing. CST has a comprehensive line of testers ranging from the low-volume service tester to the high-end, high-volume tester. In addition, CST also provides customization for proprietary module test fixtures.
