Frequently Asked Questions
Q: What’s the difference between this and standard USB hubs?
A: This IC is the controller chip used inside USB hubs – OEMs integrate it into custom PCB designs rather than using pre-assembled hubs.

Q: Does this support USB battery charging specification?
A: No, the USB2514 is a standard hub controller without dedicated charging port support.

Q: Can I operate this at 5V?
A: No, it requires 3.0-3.6V supply. Use appropriate voltage regulation for 5V systems.

Q: Is external EEPROM required?
A: The IC contains internal ROM with default settings. External EEPROM is optional for custom configurations.

Q: What cable lengths does this support downstream?
A: When properly implemented, it supports the USB 2.0 specification of 5 meters per segment.

Q: Does PCX provide design support?
A: Yes, our technical team assists with datasheet interpretation and application guidance.
