Analogix introduces USB Type-C Controller for Smartphones
With USB Type-C, a completely uniform standard for a number of cable connections is to be found in future. The new extremely narrow port is no longer dependent on the plug-in direction and can also be controlled, in addition to pure data transmission to screens, providing peripherals with up to 100 watts power.
Now the chipmaker Analogix has introduced a new USB Type-C Controller, which combines all the necessary electronics in a single chip and is particularly suitable for use in mobile devices.
The new USB Type-C single-chip controller is doing a whole range of functions which are necessary for the operation of different devices. This includes a cable configuration controller, which detects the cables and adapters used. In addition, a high-speed switch is integrated, connected between the USB and DisplayPort switch operation, if you want to use external displays. Add to this a whole range of additional electronics, which minimize signal interference and data rates to maintain high and stable.
The chip also offers all basic USB Type-C standard support, such as the power supply via USB Power Delivery to supply up to 100 watts power, data transfer rates for USB 3.1 Generation 1 standard with 5 Gb per second and for display provides support of 4K and even 8K resolution, depending on the trim level and the display used.
Overall, depending on the device class, there are six different versions of the chip. While the largest model, the ANX7428 includes all components, including 8K resolution by four DisplayPort lanes, the next smaller version for smartphones and ARM-based tablets will be designed and equipped in addition to lower construction to only about 2 DisplayPort lanes. Other models dispense then gradually to DisplayPort, high-speed switch or the USB power supply.
