Chrontel’s CH7213A 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
CH7213A 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.
The DisplayPort Alt. mode is another alternative interface
supported in the CH7213A. 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 system with CH7213A’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 CH7213A’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 CH7213A has an
internal microprocessor to handle the cable logic
communication and can be programmed for
customization according to the application of USB TypeC platforms.
For reducing the BOM cost of final products, the
CH7213A integrates all necessary components and
circuits, such as LDO, clock generation isolation circuit,
Ra
, Rd and Rp etc.
