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.
