Demultiplexers Comply With DisplayPort 1.2 And HDMI 1.4a

The PS8336A and PS8336B embark as the first DisplayPort Demultiplexer ICs that are fully compliant with the higher data rates and capabilities of DisplayPort 1.2 and HDMI 1.4a. They integrate a single Dual Mode DisplayPort 1.2 receiver with two transmitters and provide a DisplayPort 1.2 compliant output and a HDMI 1.4a compliant TMDS output. The devices support both the 5.4 Gb/s video rate and 720 Mb/s Fast AUX speed when the DisplayPort output is selected. When using the HDMI output, the they support TMDS data rates of up to 3 Gb/s, enabling HDMI pixel rates up to 300 MHz. This provides support for the higher resolution 1080p 60-fps 3D display modes described in the HDMI 1.4a specification. About the only difference between the devices is the PS8336A uses a dual-voltage 1.5V and 3.3V power supply while the PS8336B uses a single 3.3V power supply. Both are sampling now with production volumes coming in June. Available in 56-pin, 7 mm x 7 mm QFN packages, pricing for either the PS8336A or PS8336B is $1.75 each in high volume.
