(<a href=\"http:\/\/www.paradetech.com\">http:\/\/www.paradetech.com<\/a>), a leading video display and interface IC supplier, today announced a <a href=\"http:\/\/www.paradetech.com\/products\/displayport-switch-products\/ps8330-11-dp-1-2-repeater\/\">DisplayPort\u2122 Repeater IC<\/a> that is fully compliant with the higher data rates of DisplayPort 1.2.  Parade\u2019s new PS8330A\/B device also supports the Fast AUX mode of 720  Mb\/s and integrates the DDC\/AUX multiplexer (mux) needed for support of  HDMI\u2122-compatible Dual-mode DisplayPort Source devices.<\/p>\n<p>\u201cParade has taken a very active role in the development and  implementation of the DisplayPort standard. When version 1.2 of the  standard was released, it became clear that the doubling in data rates  would require cost-effective repeater ICs in many system  implementations,\u201d explains Jimmy Chiu, VP of Marketing at Parade  Technologies.<\/p>\n<p>The maximum data rate for DisplayPort increased from 2.7Gb\/s to  5.4Gb\/s when version 1.2 succeeded the earlier 1.1a. With a 5.4Gb\/s data  rate, DisplayPort can now support higher resolution displays, multiple  displays on a single channel and higher resolution 3-D displays.  DisplayPort 1.2 also added the Fast AUX mode to the AUX Channel that  increases data rates from 1Mb\/s to 720Mb\/s for this bi-directional data  path.<\/p>\n<p>Doubling the maximum data rate to 5.4Gb\/s challenges system designers  to maintain signal integrity in notebook, docking station and desktop  computer designs. At 2.7Gb\/s, PC board traces up to 10 or 12 inches can  typically be designed without a repeater IC for signal re-conditioning.  At 5.4Gb\/s, traces longer than 5 or 6 inches may require repeaters for  signal re-conditioning. Signals are also compromised as they pass  through connectors and cables between video source and sink devices,  requiring repeaters for signal re-conditioning.<\/p>\n<p>DisplayPort 1.1a repeater\/redriver devices were pioneered by Parade  starting with the PS8121ED introduced in 2008, and the company\u2019s  repeater\/redriver devices are currently used by every major PC OEM.\u00a0 By  incorporating Parade\u2019s patent-pending AUX interception or \u201csnooping\u201d  function, such repeaters respond to source-sink link training and serve  as the driver at the DisplayPort output receptacle.\u00a0 The improvement in  output signal quality is often needed to pass DisplayPort compliance  testing, and assures robust system interoperability.<\/p>\n<p><strong>Backward-Compatibility Support for HDMI and DVI Requires Dual-Mode Capability<\/strong><\/p>\n<p>Parade\u2019s PS8330A\/B devices are designed to accommodate systems  supporting Dual-Mode DisplayPort operation. An internal mux is included  to switch between the source DDC channel in DVI\/HDMI operation and the  AUX channel in DisplayPort operation.\u00a0 Unlike DisplayPort 1.1a designs,  where the lower data rate AUX mode is used (1 Mb\/s), version 1.2 Fast  AUX mode (720 Mb\/s) demands improved signal integrity offered by the  integrated mux vs. the traditional discrete implementation.<\/p>\n<p>For the main link, these new devices incorporate Parade\u2019s proven  equalizer technology for signal conditioning, and automated power  management features for reduced power consumption.<\/p>\n<p>Parade is offering two versions of its Dual-Mode DisplayPort  Repeater\/Redriver. The PS8330A uses a dual-voltage 1.5V and 3.3V power  supply; the PS8330B uses a single 3.3V power supply. Both Parade  Repeater\/Redrivers support all DisplayPort power management modes, which  allow for standby and sleep modes when the device is inactive. The  devices also support a Suspend Mode when the device recognizes an  unplugged display or the absence of video source signals. \u00a0To simplify  source system compliance testing, which is required for DisplayPort  certification, the PS8330A\/B supports test automation as defined in the  DisplayPort specification.<\/p>\n<p><strong>Price and Availability<\/strong><\/p>\n<p>The PS8330A\/B is sampling now, and production volumes will be  available in April, 2011. Both devices are available in a 7x7mm 48-pin  QFN package or a 5x5mm 40-pin TQFN package.<\/p>\n<p>The PS8330A and PS8330B will be available for $1.50 \/ea. in high volume.<\/p>\n<p><strong>About Parade Technologies, Ltd. and Parade Technologies, Inc.<\/strong><\/p>\n<p>Parade Technologies, Ltd. is a privately held fabless semiconductor  company that specializes in developing video display and high-speed  interface ICs. \u00a0The company leverages high-speed analog, mixed-signal  and digital design expertise with system level knowledge to elevate  product performance, power efficiency and customer satisfaction to new  heights.
