Video Chips Outfit ARM-Based Electronics

Providing HDMI, LVDS, HDTV, DVI, and VGA outputs, the mixed-signal CH7033, CH7034, and CH7035 convert/transmit current digital-video formats and interface with a wide range of host processors, particularly ARM mobile processors. The CH7033 video encoder drives external HD video displays using HDMI, DVI, YPbPr, and VGA. Its HDMI/DVI outputs are muxable with VGA/YPbPr outputs via a software control. Handling systems using LVDS encoding, the CH7034 offers simultaneous external analog RGB or component YPrPb outputs. Lastly, the CH7035 embarks as a cost-effective HDMI transmitter. Each device includes a scaling engine supporting HDTV resolutions up to 1080p. The CH7033 and CH7035 also include SPDIF and I²S digital audio outputs. With production volumes available in May, the devices are available in 88-pin QFN packages. The CH7035 is also available in an 81-pin BGA. Prices range from $3.85 to $4.15 each/10,000.
