Overview
The EVB-USB2534D is an evaluation and demonstration platform featuring the USB2534 USB 2.0 hub on a 4-layer RoHS compliant Printed Circuit Board (PCB). It is designed to demonstrate the unique features of this device using a low-cost PCB implementation with individual port power control for the downstream USB 2.0 ports. All downstream USB 2.0 ports include a high current port power controller to fully support USB battery charging as a high current walk-up port.
- 36-pin QFN RoHS compliant package
- Four USB 2.0 downstream hub ports with individual port power and overcurrent sense (OCS)
- High-Speed (480 Mbps), Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) compatible
- USB Battery Charging is supported on all downstream USB ports up to 2A
- Multi-Transaction Translator (MTT) is enabled
- Supports internal default hub configuration. Optionally supports configuration from external EEPROM
- Low-Cost, 4-Layer space saving design with two outer signal layers, a power inner layer and a ground inner layer
- Individual port power control with LEDs for port power indication
- Self-Powered operation
- Operates from a single voltage (12.0 VDC, regulated) external power supply
- External supply provides up to 6A of 5.0 VDC for system use and USB downstream power through an on board 5 VDC regulator
- On board MCP1725 3.3 VDC regulator provides power to the USB2534 circuits and RESETn control
- LED indicator for “Suspend” hub state (optional)
- EMI suppression provided by selection of capacitors and inner power/ground Printed Circuit Board (PCB) layers
- ESD component footprints provided (optional)
- Single crystal clock source
- Schematics, layout and bill of materials are available to minimize new product development time
