The USB2534I-1080AEN is a MTT (multi-transaction translator) USB 2.0 high-speed Hub Controller with 4 downstream ports and advanced features for embedded USB applications. The USB2534 is fully compliant with the USB 2.0 specification, USB 2.0 link power management addendum and will attach to an upstream port as a full-speed hub or as a full-/high-speed hub. The 4-port hub supports low-speed, full-speed and high-speed (if operating as a high-speed hub) downstream devices on all of the enabled downstream ports. The USB2534 has been specifically optimized for embedded systems where high performance and minimal BOM costs are critical design requirements. Standby mode power has been minimized and reference clock inputs can be aligned to the customer's specific application. Additionally, all required resistors on the USB ports are integrated into the hub, including all series termination and pull-up/pull-down resistors on the D+ and D- pins.
