SAPPHIRE HD 6850 Vapor-X Edition Graphics Card Announced

SAPPHIRE Technology has just announced a new high performance model in its extensive series of graphics cards - the HD 6850 Vapor-X Edition with SAPPHIRE exclusive Vapor-X cooler. 

The SAPPHIRE HD 6850 Vapor-X Edition has the same internal architecture as the standard model, with 960 stream processors and 48 texture processing units, but clock speeds are increased to 800MHz for the core and 1100Mhz (4.4 Gb/sec effective) for the memory giving users a considerable boost in performance.

The SAPPHIRE exclusive Vapor-X cooler ensures that the card runs quietly and efficiently. Together with other special hardware features including on-board 10-phase power control and SAPPHIRE's highly efficient, cool running second generation Black Diamond chokes this ensures there is a good margin for performance tuning (overclocking) by enthusiast users. SAPPHIRE's overclocking tool for these models - TriXX - is available free for anyone to download from a link on the SAPPHIRE website http://www.sapphiretech.com/

Eyefinity and APP Acceleration The SAPPHIRE HD 6850 Vapor-X Edition has the versatile output configuration of two DVI, one HDMI and two mini DisplayPort connectors. Using two of the DVI/HDMI outputs as well as the two DisplayPorts enables this card to support up to four monitors in Eyefinity (SLS) mode.

In the HD 6850 Vapor-X Edition the third generation UVD (Unified Video Decoder) supports MVC (Multi-view Video Coding) for the smooth decoding of Blu-Ray 3D with reduced CPU load as well as other HD file formats. Dolby TrueHD and DTS-HD Master Audio are supported, and HDMI capability is HDMI 1.4a. This provides deep colour, enhanced high resolution output for Digital Theatre applications and 3D stereoscopic support as well as 7.1 high bit-rate audio.

The multiple stream processors of the HD 6800 series can be used to accelerate other applications such as video transcoding. The latest generation of web browsers can be GPU accelerated, and this is also supported for enhanced productivity in Microsoft Office 2010.

NS puts out the trimmer serial LMK0300 of high-accuracy clock low ...

Claim NS, died, the amount to 5 high precision at the intersection of the clock and the trimmer while a series of, it has that lowers the noise of the system clock, and distribute the clock in each function module. Phase-locked loops, voltage controlled oscillators and high speed of the interface of these chips in the NS, the industry is shaking the lowest in the intersection of the clock and the trimmer can provide the precise function regular for high performance data translation and subsystem processing. The clock trimmer is most suitable for products such as wireless and wired structure, medical equipment and testing and measuring instrument,etc., this is exactly three major target markets of the above-mentioned several chips. LMK03000 that NS put out newly, LMK03000C, LMK03001, LMK03001C and LMK02000 clock trimmer built-in high-frequency phase locked loop, extremely low-noise voltage controlled oscillator and programming low-noise output system. These clocks trimmer can reduce the signal shakily and come 0.2PS representative value, if this industry shake down only the intersection of the chip and the intersection of the clock and the adjuster at the moment. All the time, engineers design the system have adopted the crystal oscillator or voltage controlled clock module consists of several chips to shake down, but this method is relatively expensive. The single chip clock trimmer which recently introduced NS can reduce the cost of the system by a wide margin, close the circuit, the reduction in energy consumption and save time and design. In addition, these clocks trimmer can produce the adjustment clock of 8 different editions, every frequency and slope of adjusting the clock are programmable, so does not need to set the distributor circuit of the clock additionally, not only can save the cost and space of the circuit board but also can reduce signals and shake. This function is most suitable for the complicated system, for example can offer the required different clock rate for different function module of this kind of system. This serial clock trimmers of NS have 3 kinds of different characteristic ranks available, all but the pin is compatible, the system design engineer only needs the design of way of a kind of printed circuit board, it is alright to be the space reserving the staging systematically, improve the flexibility in design greatly. This serial clock trimmers of NS adopt BiCMOS8 technology that this company has specially to make, this company locates the crystal plate factory of south Portland of Maine State to be responsible for producing. The chip after such advanced silicon brilliant germanium technology guarantees to be made can get the lowest shaking and optimal characteristic. The clock range that several high-accuracy clocks trimmer that NS introduces newly inputs is 1 to 200 MHz, the ones that lowered the shaking of clock signal to 0.2ps are extremely low-level. These chip built-in and high-performance integer N phase locked loop core, voltage controlled oscillator, 3 LVDSs and 5 LVPECL clocks are exported. LMK03000C and LMK03001C can shake, reduce to 0.4ps RMS signal, but LMK03000 and LMK03001 can shake, reduce to 0.8ps RMS signal. The Built-in: phase locked loop core of LMK02000 clock trimmer is connected with the externally positioned voltage-controlled crystal oscillator together. The advantage of design to can shake, reduce further signal, it reaches 0.2ps RMS to be very much low-level. NS these brand-new the intersection of clock and the intersection of trimmer and chip adopt, 48 small and exquisite guide the foot LLP to capsulate extremely, and the magnitude is all the same, let the system design engineer only need a kind of printed circuit board to conceive circuit design, can choose different type products in order to meet different shaky requirements easily. 8 Ausgangs of the clock trimmer all have a low-noise clock that distribute the passway separately, Built-in: circuit include dedicated among them but the intersection of settlement and frequency divider, phase locking circnit, can presume the intersection of delay and sector and LVDS or LVPECL clock output buffer. The system design engineer can presume separately every clock exports frequency divider and delay circuit, , but the clock that the phase place has already adjust been in order to duplicate a plurality of integer connect, the frequency of duplicating the clock reaches 785 MHz high, outputting the aslant slope can be adjusted in the range of 0 to 2.25ns, marching is 150ps. So long as the clock trimmer to adopt NS of system design engineer, can export and can enable GOE through the overall situation Pin, export, locate under the high resistant state all clock. So long as system design engineer can make to export the overall situation the pin and locking of the chip are measured LD Export and connect together, can enable all output high impedance automatically in case of not having the valid input clock. In addition, the output not in use can also locate in the high resistant state respectively. If the same system adopts a plurality of clock trimmers, the system design engineer can utilize the synchronous input pin of the chip, the flexible one adjusts different clock trimmers to the synchronous operation during start. Price and supplying the above-mentioned five chips of situation to all regard 1,000 as and purchase the unit, LMK03000C and LMK03001C two single drops of price of chip with 18.99 dollars, and LMK03000 and LMK03001 two single drops of price of chip with 15.45 too, LMK02000 12 dollars in single price of chip.
