Parade Technologies Announces PS8336A and PS8336B, the World’s First DisplayPort Demultiplexer ICs
Parade Technologies announced PS8336A and PS8336B devices , the world’s first DisplayPort Demultiplexer ICs that are fully compliant with the higher data rates and capabilities of DisplayPort 1.2 and HDMI 1.4a. Parade’s new PS8336A and PS8336B devices integrate a single Dual Mode DisplayPort 1.2 receiver with two transmitters: a DisplayPort 1.2 compliant output and a HDMI 1.4a compliant TMDS® output.
DisplayPort 1.2 implements significant advancements over the previous version, DisplayPort 1.1a. The maximum data rate increased from 2.7Gb/s to 5.4Gb/s, enabling DisplayPort 1.2 to support higher resolution displays, multiple displays on a single channel and higher resolution 3-D displays. DisplayPort 1.2 also added a Fast AUX mode to the AUX Channel that increases the data rate of this bi-directional side band signal from 1Mb/s to 720Mb/s. The PS8336A/B devices support both the 5.4Gb/s video rate and 720Mb/s Fast AUX speed when the DisplayPort output is selected.
When using the HDMI output, the PS8336A/B supports TMDS data rates of up to 3 Gb/s, enabling HDMI pixel rates up to 300 MHz. This provides support for the new, higher resolution 1080p 60fps 3D display modes described in the HDMI 1.4a specification.
Parade’s PS8336A/B devices are designed to accommodate Dual-Mode DisplayPort operation. The internal demultiplexer switches the Dual Mode DisplayPort Source between DisplayPort and TMDS outputs—the TMDS output is compatible with both HDMI and DVI displays. When using the DisplayPort output, the devices behave like a DisplayPort repeater / redriver. Parade’s own AUX Channel interception technology is used to passively monitor the DisplayPort training signals between the Source and Sink and automatically set DisplayPort lane count, amplitude, and output pre-emphasis levels for the Main Link. For the DisplayPort input receiver, these devices incorporate Parade’s proven equalizer technology for input signal conditioning, enabling automatic compensation for variations in cable, connector and PCB trace signal losses to ensure performance robustness.
Parade is offering two versions of its Dual-Mode DisplayPort Demultiplexer. The PS8336A uses a dual-voltage 1.5V and 3.3V power supply; the PS8336B uses a single 3.3V power supply.
The PS8336A/B is sampling now, and production volumes will be available in June 2011. Both devices are available in a 7x7mm 56-pin QFN package.
The PS8336A and PS8336B will be available for $1.75 /ea. in high volume.
