Cypress Samples High-Performance PLL Clock Driver For Advanced DDR400 Memory Modules.Business Editors/High-Tech Writers SAN JOSE, Calif.--(BUSINESS WIRE)--March 18, 2004 230 MHz Timing Device Supports PC3200 Memory Modules For Servers, Workstation, and Routers Cypress Semiconductor Corporation (NYSE NYSE See: New York Stock Exchange :CY), a world leader in timing technology solutions, today announced sampling of the CY2SSTV SSTV Slow-Scan Television 857-32, one of the industry's fastest phase-locked loop (PLL PLL - phase-locked loop ) clock drivers for registered dual inline memory modules (DIMMs). Operating at clock frequencies up to 230 MHz, the new device exceeds the Joint Electron Device Engineering Council (JEDEC The division of the Electronic Industries Alliance (EIA) that deals with semiconductor standards (officially, the JEDEC Solid State Technology Association of EIA). JEDEC was formed in 1958 when the Joint Electron Tube Engineering Council (JETEC) split into two Joint Electron Device ) specification for the DDR (Double Data Rate) Refers to an SDRAM memory chip that increases performance by doubling the effective data rate of the frontside bus. For more details, see SDRAM. DDR - Double Data Rate Random Access Memory 400 standard. Cypress offers a full portfolio of DDR1 PLL clock drivers as well as registered buffers for registered DIMM (Dual In-Line Memory Module) A printed circuit board that holds memory chips and plugs into a DIMM socket on the motherboard. See memory module. DIMM - Dual In-Line Memory Module modules ranging from PC2100 up to PC3200 speeds. The CY2SSTV857-32 is a high-performance, low-skew, low-jitter zero-delay buffer (ZDB) designed to distribute differential clocks in high-speed DIMMs in applications such as servers, workstations, routers and switches. The new device has very low clock skew and jitter characteristics, ensuring clock signal integrity and superior reliability. "The CY2SSTV857-32 is the ideal clock driver solution for high performance DIMMs that transfer multiple gigabytes of data per second," said Rob Raghavan, senior product marketing manager for Cypress's Timing Technology Division. "Cypress is fully dedicated to the registered DIMM market with products and development plans that span from DDR1 through DDR3 speeds." The CY2SSTV857-32 generates ten differential pair clock outputs from one differential pair clock input. The CY2SSTV857-32 also features differential feedback clock outputs and inputs, enabling it to serve as a zero delay buffer (ZDB). When used as a ZDB in nested clock trees, the CY2SSTV857-32 locks onto the input reference and translates it with near-zero delay to low-skew outputs. Availability The CY2SSTV857-32 is available now in a 48-pin TSSOP TSSOP Thin Shrink Small Outline Package TSSOP Thin Scale Small Outline Package and 40-pin MLF/QFN. The device is available in both commercial and full-industrial temperature ranges.
