Parade Technologies Introduces Two New DisplayPortTM Switch Products.

New PS8318 and PS8312 DisplayPort(TM) Demux Products Leverage Proven Advanced Equalizer and Aux Channel Link Training Combination to Assure DisplayPort Source Compliance for Desktop, Notebook, and Docking Station PC Applications

SUNNYVALE, Calif. -- Parade Technologies Ltd. (www.paradetech.com), a leading innovator of digital video interface products, has introduced two new DisplayPort(TM) interface products for PC and Notebook applications. The PS8318 and PS8312 are DisplayPort demux (Demultiplexer) integrated circuits designed for video source systems. Each device provides two selectable digital video outputs from a single digital video input.

The PS8318 provides two dual-mode DisplayPort outputs from a single dual-mode DisplayPort input. The PS8312 is a similar product, but has one dual-mode DisplayPort, and one DVI or HDMI(TM)output that includes an integrated level-shifting circuit. The DVI/HDMI output can directly drive a DVI or HDMI system receptacle. Applications include desktop PCs, notebooks, and docking stations.

The PS8318 and PS8312 can be used for signal distribution within the system, and they can directly drive the digital video output receptacles. Unlike other DisplayPort demux products in the market, the PS8318 and PS8312 both include an advanced equalizer circuit at the device input to remove signal distortion due to PCB traces, cables and/or connectors. They also include advanced link training to provide optimized regenerated output signal characteristics that meet DisplayPort specification and compliance requirements.

Both the PS8318 and PS8312 accept "dual-mode" DisplayPort signaling from an upstream GPU (Graphics Processing Unit) video source. A dual-mode source can encode video data in either DisplayPort or DVI/HDMI protocol. The PS8318 and PS8312 selectively switch this dual-mode signal to the required output format.

By providing two dual-mode DisplayPort outputs, the PS8318 is well suited for video signal routing within a notebook PC. In a typical application, the PS8318 can be used to switch the GPU's output video between the display panel and the DisplayPort output receptacle. Alternately, it can be used to switch between the output receptacle and docking station interface.

The PS8312 has one dual-mode DisplayPort output and one DVI/HDMI output, making it ideal for driving a DisplayPort and DVI or HDMI receptacle pair on the system interface panel. Automatic port switching simplifies the user system configuration.

"With our ongoing involvement in the development of the DisplayPort standard and infrastructure, it became clear that suitable signal routing devices were needed," explains Jimmy Chiu, VP of Marketing at Parade. "The PS8318 was developed particularly for the needs of the notebook market. The PS8312 can be used in a desktop PC, notebook or docking station since it enables the retention of DVI and/or HDMI outputs without adding video output ports to the GPU, or requiring the use of an external DP-to-DVI/HDMI dongle. For both devices we added the advanced equalizer and link training circuits, which our customers favor for DisplayPort compliance testing reasons."

Advanced Signal Conditioning Equalizer and Link Training Simplifies Board Design

Both the PS8318 and PS8312 incorporate Parade Technologies' unsurpassed DisplayPort repeater architecture that was previously introduced in the PS8121ED DisplayPort Repeater. On the device input, an advanced equalizer is used to remove DisplayPort signal distortion imposed by PCB traces and internal system connectors. On the DisplayPort output, Parade Technologies' proprietary 'Aux Channel interceptor' circuit (Patent pending) is used to monitor the DisplayPort Aux Channel communication between the Source and Sink systems. The output voltage swing and pre-emphasis level are automatically adjusted according to the Sink system request during the Link Training period. Also adjusted is the number of Main Link lanes and Aux Channel managed power states.

"Without this kind of signal reconditioning," explains Jimmy Chiu, "many new DisplayPort systems were having trouble meeting DisplayPort PHY compliance testing. This is true with both mother boards and docking stations, especially when routing the DisplayPort signal from an integrated chip set or MXM graphics card. We think systems designers often underestimate the difficulty in routing the 2.7 Gbps DisplayPort signals. The new Parade Technologies devices can actually allow designers to save money by reducing the number of PCB layers otherwise required for low signal distortion -- the PS8318 and PS8312 will automatically remove the distortion imposed by a less expensive PCB design."

Price and Availability

The PS8318 and PS8312 are each packaged in an 8x8mm 56-pin QFN package. They can be operated through device pin control or through I2C bus interface from the system host. Both devices use a single 3.3V supply, consume low power, and feature automatic power management. They are compliant with DisplayPort Standard Version 1.1a and meet the DisplayPort PHY Compliance Test Standard Version 1.1. The PS8312 DVI/HDMI interface is complaint with HDMI Specification Version 1.3a. The PS8312 also includes an integrated EMI filter for the DVI/HDMI output port.

The PS8318 and PS8312 are available in prototype quantities now, and sell for $1.45 and $1.60, respectively, in volume.
