Chrontel’s CH7213C 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.

CH7213C’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 CH7213C. 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

CH7213C’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

CH7213C’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 CH7213C 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

CH7213C integrates all necessary components and

circuits, such as LDO, clock generation isolation circuit,

Ra

, Rd and Rp etc.
