The USB3503A-1-GL-TR is an USB 2.0 HSIC High-Speed Hub Controller with HSIC upstream connectivity and three USB 2.0 downstream ports. The USB3503 operates as a hi-speed hub and supports low-speed, full-speed and hi-speed downstream devices on all of the enabled downstream ports. It has been specifically optimized for mobile embedded applications. The pin-count has been reduced by optimizing the USB3503 for mobile battery-powered embedded systems where power consumption and minimal BOM are critical design requirements. Standby mode power has been minimized. Instead of a dedicated crystal, reference clock inputs are aligned to mobile applications. Flexible integrated power regulators ease integration into battery powered devices. All required resistors on the USB ports are integrated into the hub. This includes all series termination resistors on D+ and D- pins and all required pull-down resistors on D+ and D- pins.
