GENERAL DESCRIPTION Chrontel¡¯s CH7213D is a low cost USB Type-C logic controller. The device is targeted for system designers implementing USB Type-C devices with DisplayPort capabilities and USB Power Delivery 3.0 support. CH7213D¡¯s robust Power Delivery 3.0 module using the BMC protocol can enable USB Type-C devices operating in various power management roles including Consumer and Provider. The DisplayPort Alt. mode is another alternative interface supported in the CH7213D. A builtin Billboard Class can be automatically exposed to the USB 2.0 D+/- bus if a Type-C PD Source (DFP) does not equip USB Type-C Alt. Mode features that support DisplayPort signal transmission. The system with CH7213D¡¯s DisplayPort Alt. mode enabled can be programmed to support Type-C to DisplayPort display or DisplayPort to a Type-C DP Alt. mode monitor. The CH7213D¡¯s bi-directional signal converter for the DisplayPort HPD (hot plug ***ection) and VDM (Vendor Defined Message) is capable of translating the HPD to the appropriated VDM to Type-C DP device and vice versa. In addition to hardware support of PHY and Link layers, the CH7213D has an internal microprocessor to handle the cable logic communication and can be programmed for customization according to the application of USB Type-C platforms. For reducing the BOM cost of final products, the CH7213D integrates all necessary components and circuits, such as LDO, clock generation isolation circuit, Ra, Rd and Rp etc.
