Re-timer and USB-C switch speeds 8x4k video
Believed to be the first integrated switch that can switch DisplayPort version 1.3 and 1.4 at 8.1Gbit/s and USB 3.1 Gen2 10Gbit/s, ANX7440/30 supports a single USB-C port for notebooks, desktop PCs and convertible laptops.
Operation at 10Gbit/s enables faster communication between devices and 8 x4k video output, says Analogix Semiconductor.
The ANX7440 is an integrated 10Gbit/s re-timer and USB-C switch for DisplayPort over USB-C ports. The ANX7430 is an integrated 10Gbit/ re-timer and USB-C switch for USB 3.1 Gen2 USB-C ports. Both use the company’s high-speed signalling technology and are designed to the USB 3.1, DisplayPort 1.4, and Intel USB 3.1 repeater and active switch specifications. Features include an integrated USB 3.1 re-timer, DisplayPort HBR3 re-timer, 6×4 10Gbit/s mux, and SBU/AUX mux for USB-C DisplayPort alt mode applications. Loss compensation recovers up to 23dB channel loss for USB 3.1 Gen2 10Gbit/s and up to 20dB channel loss for DisplayPort HBR3 8.1Gbit/s. According to the company, it also simplifies PCB routing for 10Gbit/s notebook, desktop PC, and USB 3.1 enabled mobile device docking station designs.
It also meets the need for graphics processors across computing devices which are now available supporting 8.1Gbit/s link bandwidth, featured in DisplayPort version 1.3 and 1.4. Used as signal conditioners, the ANX7440/30 help to implement this feature over a range of devices, accelerating it into mainstream consumer devices.
It also improves performance of USB 3.1 external hard drives connected through a docking station, points out the company. DisplayPort over USB-C allows devices to output video resolutions up to 8Kx4K, to deliver an immersive virtual reality (VR) or augmented reality (AR) experience. Its ability to recover and reinstate high-speed signals reduces the thickness and enables longer cables to be used.
Sampling will begin in Q4, with mass production in Q2, 2017.
