The DOCK220 supports Dual Role USB Type-C Power Delivery 3.0 for both PC (Windows and Linux) and MacBook hosts. As a PD Source it supplies up to 85W at the following levels:
- 5Vdc @ 3A
- 9Vdc @ 3A
- 15Vdc @ 3A
- 20V @ 4.25A
The DOCK220 interfaces and ports include:
- 1 DRP USB Type-C Female Thunderbolt 3 with PD 3.0 to 85W
- 1 DFP USB Type-C Female Thunderbolt with DP1.2 Alternate Mode 4096×2160 p60
- 1 DFP DP1.2 4096×2160 p60
- 2 DFP USB 3.0 Type-A SuperSpeed ports front/back both supporting BC1.2 charging
- 1 DFP USB 3.1 Gen 1 Type-C SuperSpeed port front
- 1 Gigabit Ethernet RJ-45 with WOL
- 1 3.5mm Female Stereo Audio Output Port
- 1 3.5mm Female Stereo Audio Input Port
- Purple Power Applied LED front
- Kensington Lock Slot
- Targus VESA100 Bracket Mounting for Dell Monitors
The DOCK220 supports up to dual DP1.2 video to dual 4096×2160 p60 (cinema 4K2K) display monitors. Windows PC OEMs have implemented a subset of Thunderbolt features for some PC models, especially with first generation USB-C Thunderbolt ports, see Thunderbolt 3 Cable, Port and Power Performance Expectations. Many hosts do not support supplying two discrete full 4-lane DisplayPort 1.2 streams to render two separate 4K2Kp60 monitor displays, see Thunderbolt 3 USB Type-C.
Most of the Thunderbolt ports on the latest MacBooks do support dual DP1.2 (for dual 4K2Kp60) and since the DOCK220 supports up to 85W of PD, its perfect for today’s Macbooks. To determine if a PC platform supports dual discrete video click here. For hosts that support dual video on its Thunderbolt port, i.e. the Dell XPS13 9360, one DP monitor is connected utilizing the DP 1.2 port on the DOCK210 and the second monitor to the Downstream Facing USB Type-C Thunderbolt port utilizing it as a DP 1.2 Alternate Mode port.
Many of the PC OEM docks are utilizing Multi-Stream Transport (MST) and can claim dual video support for their own respective Thunderbolt PC when used with their own proprietary Thunderbolt docking station offerings containing an MST switch. However, most cannot claim dual 4K2Kp60 when splitting the DP1.2 stream, see DisplayPort Alternate Mode vs. DP Alt. Mode. By not implementing an MST switch in the DOCK220, Targus has a Thunderbolt dock that supports dual 4K2Kp60 when used with a dual DP 1.2 host, and doesn’t require video compression or MST splitting.
When used with a Thunderbolt host that has only one DP 1.2 stream, the Down Stream Facing Thunderbolt port on the DOCK220 can be used for high speed storage, i.e. a Thunderbolt 3 drive like the one shown here. This makes the DOCK220 a perfect fit for many applications requiring high-speed access to storage and high-resolution video like CAD/CAM and video editing.
Comparison to the DOCK410 and DOCK180
The DOCK410 takes advantage of the native DisplayPort data on Thunderbolt 3 and DisplayPort hosts and so it is recommended for USB Type-C DisplayPort Alternate Mode and will work with USB Type-C Thunderbolt 3 ports, see Optimizing Your Targus DOCK410 Experience. It will not work with USB Type-C 3.1 Gen 1/2 ports.
The DOCK180 uses the industry standard DL-6950 adaptive compression software for USB SuperSpeed available on USB Type-C Thunderbolt 3, USB Type-C DP Alt. Mode, and USB Type-C 3.1 Gen 1/2 ports. Its the USB Type-C that always works, see Type-C That Always Works.
The DOCK220 takes advantage of the native DisplayPort data on Thunderbolt 3 hosts and is recommended for USB Type-C Thunderbolt hosts. It will not work with USB Type-C DP Alt. Mode or USB Type-C 3.1 Gen 1/2 ports.
