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.
