Chrontel, Inc., announced a new HDMI CEC (Consumer Electronic Control) IC, the CH7322. The CH7322 adds CEC functionality to digital TVs, PCs, video recorders and other A/V products that support the popular HDMI standard. With CEC capability embedded into consumer products, a viewer can control multiple HDMI-linked devices with a single remote control, enhancing the user experience.
Low-cost Device Adds CEC-Capability to CE and PC Designs
The CH7322 is the world’s first stand-alone CEC chip without an EEPROM and an additional CPU chip. It offers designers a way to augment their existing A/V designs for both PCs and consumer products with minimal incremental cost.
In addition to HDMI features incorporated into PC desktop or laptop graphic chipsets, many A/V products employ MPEG decoders or DTV-on-chip ICs that have integrated HDMI transmitters. The CH7322 allows such designs to add CEC functionality without the cost of an additional, redundant HDMI-CEC combination transmitter and a CPU for CEC message processing. The CH7322 can also be coupled with HDMI transmitter ICs that do not integrate the CEC capability. The CH7322 can also be designed into HDTVs with multiple HDMI inputs for handling CEC messages.
