11 / 71 page  11 TUSB422 www.ti.com SLLSEW6 – NOVEMBER 2016 Product Folder Links: TUSB422 Submit Documentation Feedback Copyright © 2016, Texas Instruments Incorporated Functional Block Diagram (continued) 7.2.1 Cables, Adapters, and Direct Connect Devices Type-C Specification 1.2 defines several cables, plugs and receptacles to be used to attach ports. TUSB422 supports all cables, receptacles, and plugs. 7.2.1.1 USB Type-C receptacles and Plugs • USB Type-C receptacle for USB2.0 and USB3.1 and full-featured platforms and devices • USB Full-Featured Type-C plug • USB2.0 Type-C Plug 7.2.1.2 USB Type-C Cables • USB Full-featured Type-C cable with USB3.1 full featured plug • USB2.0 Type-C cable with USB2.0 plug • Captive cable with either a USB Full featured plug or USB2.0 plug 7.2.1.3 Direct Connect Devices TUSB422 supports the attaching and detaching of a direct connect device such as a cradle dock or captive cable. 7.3 Feature Description 7.3.1 USB PD I2C Type-C Port Controller Interface (TCPC) The TUSB422 provides up to 1Mbps I2C USB Type-C Port Controller Interface (TCPC) interface and register set allowing for control by external processor. The TUSB422 implements the following optional TCPC features. • Up to 24 V VBUS Measurement and Alarms • Default, 1.5 A, and 3 A Source Resistor (Rp) advertisement • Source VCONN • VCONN overcurrent fault detection 7.3.2 USB PD BMC PHY The TUSB422 contains a USB Power Delivery BMC (Bi-phase Mark coded) Baseband phy. The TCPM can enable the TUSB422’s USB PD BMC phy for any of the following conditions when the TUSB422 is in Attached.SNK, Attach.SRC, DebugAccessory, or PoweredAccessory state: • Receiver Detect Register is non-zero The USB PD phy will always be disabled when the TUSB422 is in the unattached mode. The TUSB422 PD BMC phy receiver threshold will be set based on the value of the POWER_ROLE field in the Message Header Info register. The default receiver threshold can be changed by setting the VIX_PD and VIX_PD_OVERRIDE fields in the PHY BMC RX Control register. Table 1. Power Role POWER-ROLE VIH VIL 0 VIH(PD_SRC) VIL(PD_SRC) 1 VIH(PD_SNK) VIL(PD_SNK) 7.3.3 DFP (Downstream Facing Port) The TUSB422 can be used in applications in which USB devices are connected too. For example, in a desktop application the Type-C port(s) must be able to determine when a device is attached and enable both power (in the form of VBUS) and datapath (either USB data and/or Alternate Mode data like DisplayPort) to attached device. The TUSB422 can be used in a DFP application by programming the Role Control register to 0x05. This presents Rp on both of TUSB422 CC pins. When configured as a DFP, the TUSB422 can be used to control the sourcing of VCONN. Control of VBUS source path must be handled outside of the TUSB422. |
