Question:
What are the differences between Cypress Type-C Hubs and Docks?
Answer:
- EZ-USB® HX3PD is the industry's first 7-port USB 3.1 Gen 2 Type-C Hub with USB Power Delivery 3.0 (PD 3.0), supporting five downstream USB 3.1 Gen 2 ports (three Type-C ports and two Type-A ports) and two downstream USB 2.0 ports. HX3PD is Cypress' most integrated USB hub, integrating a dual-port PD 3.0 controller (which provides PD 3.0 on one US and one DS Type-C port), a 7-port hub, and a Dock Management controller reducing Bill of Material (BOM) cost and solution footprint, making it ideal for USB Type-C docks, monitors, and standalone hubs.
- EZ-PD™ CCG4 Monitor/Dock Solution enables connectivity between a USB Type-C host system on the upstream port and multiple display and data devices on the downstream port. This solution has a USB Type-C receptacle on the upstream port which supports data, power, and display. On the downstream port, this solution supports one USB 3.0 Type-C (display, power, and data) port, three USB 3.0 Type-A ports, two USB 2.0 Type-A ports, one HDMI, and a Gigabit Ethernet port.
- EZ-USB® HX3C is Cypress’ USB 3.0 compliant Hub-controller with Type-C and USB Power Delivery 2.0 supporting three downstream USB 3.0 ports (one Type-C and two Type-A). As HX3C does not support the latest USB and Power Delivery standards (PD 3.0), it is not recommended for new designs.
EZ-USB® HX3C Monitor/Dock Solution enables connectivity between a USB Type-C connector of a host system on the upstream port and multiple display and data connectors on the downstream ports. This solution has a USB Type-C receptacle on the upstream port which supports data, power, and display. On the downstream port, the solution supports one USB Type-A port, one Gigabit Ethernet port, one Display port, and one USB Type-C port. This solution does not support the latest PD protocol rev 3.0, and hence is not recommended for new designs.
