Describe

Chrontel’s CH7214C 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 2.0 support. The CH7214C integrates the USB Type-C plug orientation and attached detection mechanism on the CC (Channel Communication) pins. Its robust Power Delivery 2.0 module using the BMC protocol can enable USB Type-C devices operating in various power management roles including Consumer, Provider and Power Role Swap. CH7214C also supports the battery charging with specification revision 1.2.The DisplayPort Alt. mode is another alternative interface supported in the CH7214C. A built-in 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 CH7214C’s bi-directional signal converter for the DisplayPort HPD (hot plug detection) 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 CH7214C 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 In order to save the BOM cost of the end product such as cable, the CH7214C also integrates all necessary
components and circuits, such as LDO, clock generation,isolation circuit, Ra, Rd and Rp etc.
