In a blog not too long ago, I spoke in detail on our new VX6BxG variants of the ArcticLink III family, which support an MIPI input to LVDS and RGB output architecture. This product is targeted primarily at tablets with a need for a secondary video output, most often used for MHL or HDMI purposes. I detailed a number of technical reasons why this device is needed in today’s common tablet architectures that suffer from a lack of (a) dual concurrent output support and (b) native MHL/HDMI support from the CPU.
So, with no further adieu, we are announcing the newest silicon variants of the ArcticLink III, the VX6BxH and the BX6BxH.
These VX6BxH silicon variants take a single MIPI-DSI input from the host CPU, and output both an LVDS signal (for the embedded display) and a MIPI-DSI signal (for secondary output purposes, such as MHL transmitters). In terms of function and purpose, they are very similar to the aforementioned VX6BxG, differing in the output interfaces supported.
We developed these devices to support customers who have decided to use MHL transmitters which require a MIPI-DSI input. There are some technical advantages and disadvantages to using either RGB or MIPI for the secondary output purposes; power consumption, number of circuit traces required, complexity of design, etc… Suffice to say that for the secondary output purposes, neither MIPI-DSI or RGB presents an overwhelming competitive advantage versus the other, hence QuickLogic’s support of both interfaces.
The VX6BxH will be offering in two variants, while the BX6BxH will have two as well. Of course, the VX6 contains QuickLogic’s VEE and DPO technologies, allowing for display sunlight viewability and 25% average system-level power savings. The BX6 are bridge-only versions, offering a lower price while remaining pin-identical with their VX6 counterparts. Here’s a quick primer on those variants:
