EZ-PD™ CCG3 USB Type-C Charge-Through Dongle
The EZ-PD™ CCG3 USB Type-C Charge-Through Dongle solution enables connectivity between a USB Type-C Notebook and HDMI Display, legacy USB device and Gigabit Ethernet while also connecting a USB Type-C charging cable. The Charge-Through Dongle solution allows simultaneous HDMI display, Superspeed data transfers, Ethernet connection and charging USB Type-C Notebook. Charge-Through Dongle is also widely known as Multiport Adapter.
The EZ-PD™ CCG3 fully supports the latest Power Delivery 3.0 specification especially the fast role swap feature. Fast Role Swap enables externally powered dongle to rapidly switch to bus power when their external power supply is removed. For more details, refer to Section 6.3.17 (FR_Swap Message) in the USB-PD 3.0 specification. This solution is designed to be fully interoperable with revision 3.0 of the USB Power Delivery specification as well as its previous revision (USB Power Delivery 2.0). The CCG3 Charge-Through reference design is supported by Cypress's EZ-PD Software Development Kit version 3.0 (EZ-PD SDK v3.0).
The EZ-PD™ CCG3 (CYPD3123) available in a 40-QFN package, integrates a complete USB Type-C, USB Power Delivery, USB Billboard, SBU switch and terminations on the AUX lines solution in a single chip. The EZ-PD™ CCG2 (CYPD2122) available in 24-QFN package, is a Type-C port controller which acts a Upstream Facing Port (UFP) and sinks power when connected to the Type-C chargers. This Charge-Through Dongle solution also implements Cypress's USB SuperSpeed Hub controller HX3 (CYUSB3304-68LTXI) available in 68-QFN package, Low-power single chip USB 3.0 to Gigabit Ethernet Bridge Controller GX3 (CYUSB3610-68LTXC) available in 68-QFN package.
CCG3 CYPD3123 is factory pre-programmed and is available for sample in October 2016. CCG2 CYPD2122 is available with I2C bootloader, application firmware (available in SDK3.0 project) can be programmed using Cypress's EZ-PD Configuration Utility. Cypress has developed reference design schematic will enable customers to speed up their design and development cycle.
