LVDS transmitter meets new Intel specs
A new LVDS transmitter is the first of its type to comply with Intel's new, proprietary SDVO (serial digital video output) PC interface specification.
Chrontel is now sampling a new LVDS (low voltage differential signal) transmitter, the CH7308A, which is the world's first LDVS chip that complies with Intel's new, proprietary SDVO (serial digital video output) PC interface specification LVDS devices are mixed-signal ICs (integrated circuits) that are used in almost every laptop PC to transmit display pixel data from the CPU motherboard, across the open hinge of the laptop, to the flat panel display

Video chips gain Centrino compatibility
Chrontel has customised its extensive product line to support Intel's new Centrino mobile technology.
Intel's latest PCI Express chipsets - the Intel 915G, 915GV and 910GL Express Chipsets - include an IGD (integrated graphics device) that delivers cost-competitive 3D, 2D and video capabilities.
These IGD chipsets use Intel's new SDVO specification to drive external displays with a high-speed serial data interface.
Laptop and LCD-PC manufacturers that design new PCs using these PCI Express chipsets will need to design-in LDVS transmitters that comply with the new SDVO interface.
Chrontel's CH7308A transmitter is the industry's first LVDS device that supports the 1-2Gbit/s high-speed SDVO interface specification.
The CH7308A supports output rates up to 165Mpixel/s, suitable for driving flat panel displays with resolutions up to UXGA (1600 x 1200 pixel) at a 60Hz refresh rate.
A natural extension of Chrontel's widely-adopted LVDS product line, the new Chrontel chip is already being designed into the latest laptop and LCD-PC designs by leading Japanese PC OEMs.
The mixed-signal CH7308A is also the latest in a family of SDVO-compliant devices that Chrontel began releasing last quarter.
"Laptop and LCD-PC designers are eager to leverage the cost advantage offered by Intel's integrated graphics devices", explained Dr David Soo, Chrontel President and CEO.
"As a leading vendor of LVDS solutions, we are pleased to offer our PC customers an SDVO-compliant solution that enables them to utilise the latest PCI Express chipsets".
The Chrontel CH7308A is currently sampling, and production volumes will be available in Q1 2005.
The device is offered in a low-cost 64-pin LQFP package, and comes complete with Windows driver support.
The CH7308A is priced at $4.50 in 10,000 piece quantities.
