Native HDMI over Type-C Alternate Mode | 赛普拉斯半导体
HDMI® over USB-C™
HDMI is available today over USB-C, but it is costly
Current solutions require DisplayPort™ Alternate Mode, a DP to HDMI converter and VBUS DC/DC converters
HDMI over USB-C Alternate Mode is a simpler, cost-effective solution
Native HDMI from new HDMI enabled sources, over USB-C pins
Full HDMI 1.4b functionality without DP to HDMI converters or DC/DC converters
HDMI Alternate Mode is easy to use, and HDMI is a worldwide standard
Spec released by HDMI SIG on Sept, 2016
Combines the most popular connectivity solutions, USB-C and HDMI, together
Enables a simple USB-C to HDMI cable with no adapters or converters
Cypress Enables the Industry's First Native HDMI over USB-C Solution
Based on Cypress EZ-PD™ controllers, next-generation laptops, smartphones, tablets, digital cameras and other HDMI sources with USB-C connectors can connect directly to HDMI sinks, such as HD and 4K monitors, TVs and projectors, using only a simple USB-C to HDMI cable. The EZ-PD controllers support the new native HDMI Alternate Mode for USB Type-C, along with USB Type-C standard support for audio, video and data protocols, as well as USB Power Delivery (PD) for fast charging.
All HD and 4K televisions include HDMI connections, but connecting source devices previously required adapters or converters that did not enable all native HDMI features. With the Cypress HDMI alternate mode solution, manufacturers can now utilize native HDMI features via USB Type-C connectors.
Cypress's CCG2, 3, 4 solutions can be used for HDMI sources, and CCG3 is ideal for USB-C to HDMI cables:
- Enabling native HDMI over USB-C, with no protocol conversion
- Integrating ARM® Cortex®-M0 with dual 64KB flash blocks for fail-safe firmware updates, Crypto Engine supporting USB Authentication and USB Billboard Controller for Alternate Modes
- Shipping with USB-IF compliant, factory-programmed firmware
- Including a full-featured EZ-PD Software Development Kit to keep up with the latest USB IF standards
Cypresss CY4500 EZ-PD Protocol Analyzer supports protocol analysis of the USB-PD and USB Type-C specifications. It performs non-intrusive probing and captures accurate protocol messages on the CC line. This analyzer consists of Cypresss programmable MCU (PSoC® 5LP), which monitors data on the CC lines and sends this data to the host application over a USB interface. The Type-C plug and Type-C receptacle on this analyzer provide a pass-through for the Power Delivery (PD) Packets transmitted between each Type-C PD connection.
The EZ-PD™ CY4521 CCG2 Evaluation Kit (EVK) is based on the CCG2 product family (CYPD2xxx) of Cypress's USB Type-C controller with Power Delivery.
The EZ-PD™ CY4531 CCG3 Evaluation Kit (EVK) is based on the CCG3 product family (CYPD3xxx) of Cypress's USB Type-C controller with Power Delivery.
The CY4541 EZ-PD CCG4 Evaluation Kit (EVK) is based on the Cypresss CCG4 dual port Type-C Power Delivery (PD) controllers. EZ-PD CCG4 is a dual USB Type-C controller that complies with the latest USB Type-C and PD standards
Cypress provides the EZ-PD CCGx Software Development Kit (SDK) which facilitates the development of a variety of solutions using the various CCG controllers, such as CCG2, CCG3 and CCG4. The SDK includes a USB Type-C and USB-PD specification compliant firmware stack, reference firmware applications and documentation.
