Chrontel offers HDMI encoder chip for netbooks and nettops

SAN JOSE, USA: Chrontel, a leading provider of video interface technologies, has announced a low-power video IC for Internet computers, including the latest netbook and nettop systems.

Designed specifically to interface with highly integrated low-power processors that rely on LVDS video outputs -- like Intel’s recently announced N450, D410 and D510 Atom processors -- Chrontel’s mixed-signal CH7036 IC converts LVDS inputs into HDMI, DVI or VGA video outputs for external displays and digital televisions.

The CH7036 also has an additional output port that can retransmit graphic data in LVDS format to the netbook’s display while one of the external video outputs is enabled.

The CH7036 has a single-channel LVDS receiver and transmitter that is compatible with resolutions up to 1366 x 768. The device’s integrated frame buffer scaler and HDMI/DVI encoder supports output resolutions up to 1080p. The CH7036 also incorporates three high-speed 10-bit DACs for VGA output.

The device has built-in CEC support and two-channel SPDIF and I2S digital audio output. The CH7036 also takes the advantage of its high-speed internal SDRAM frame buffer, enabling image upsizing/downsizing, zooming and 90/180/270 image rotation.

"Low power processors like Intel’s very successful Atom line, have integrated graphic controllers. They typically rely on LVDS for video interface," said Dr. David Soo, Chrontel president and CEO.

"To enable netbook and nettop designers to add an HDMI option for high-def display, a conversion chip is required. Our customers appreciate sourcing this device from an established vendor like Chrontel. We have years of experience working closely with both computer ODMs and processor designers to develop proven video interface solutions like the CH7036."

Chrontel CH7036 samples are currently available, and production volumes will be available in July 2010. The device is offered in an 88-pin QFN package, priced at $4.50 each in 10,000 piece quantities.
