EVB-USB82514

The SMSC Automotive Grade USB 2.0 4-Port Hub is designed, fabricated, tested, characterized and qualified for automotive applications. The USB82514 MultiTRAK is a low-power, OEM configurable, full featured Hi-Speed USB 2.0 compliant hub contnroller IC with four down-stream ports for embedded USB solutions. The EVB-USB82514Q36-Bas 36-Pin QFN Evaluation Board demonstrates a stand alone application for the hub with all the features listed below and demonstrates the advanced power saving options and configurable port assignments.

Low pin count USB82514 36 - pin QFN package Hi-Speed (480 Mbits/s), Full-Speed (12 Mbits/s), and Low-Speed (1.5 Mbits/s) compatible Operation from a single voltage (+5.0 VDC, regulated) 'wall wart' external power supply Low cost 4-layer design: two outer signal layers - power inner layers - ground inner layers Optional pull-up resistors for disabling individual downstream ports Self-powered operation Multi-transaction translator enabled Support of internal default hub configuration Single onboard +3.3 VDC regulator Single crystal clock sourc Individual port over-current sensing Individual port power control Port over-current sensing (OCS)/port power control interface with LEDs for port power indication Red LED indicator for active hub state (not suspend) EMI suppression provided by ferrite beads, selection of capacitors, and internal power/ground layers. ESD protection up to 25 kV direct contact to USB signals provided with diode bridges and common mode chokes.
