Maxim Unveils SmartSleep Technology to Control Video Power Consumption

Maxim Integrated Products, Inc. introduced the MAX9508/MAX9512 – analog standard-definition video filters equipped with the company's SmartSleep technology. The new SmartSleep technique intelligently controls power consumption by turning on the device only when the video input signal and the output load are detected. Using SmartSleep technology, the 4-channel MAX9508 and MAX9512 substantially reduce power consumption by shutting down the filters and amplifiers of the unused channels. These new video filters are available in a tiny 3mm x 3mm TQFN package.

In addition to the power-saving SmartSleep technology, the MAX9508 video filter amplifier provides bidirectional video support, which makes the device extremely versatile. The MAX9508 can be used for many power-sensitive applications including portable DVD players, set-top boxes, (STB) and portable media players (PMP). The MAX9508 contains three reconstruction filters, four video amplifiers, and a pull-down switch at one of the two CVBS outputs. The internal switch can be used as a 2:1 mux to select between two input sources. That same switch can also control the bidirectional video signals at the CVBS video connections without needing separate switches or relays. This latter feature is particularly useful for portable DVD players, which often use the same connector to drive a composite video output and to accept an external video signal to display on the portable DVD player's LCD panel. The two CVBS outputs can be dc-coupled and drive up to two video loads to ground, or ac-coupled to one video load.

Adding a Y/C mixer, the MAX9512 video filter amplifier with SmartSleep technology is designed specifically for portable media players. The Y/C-to-CVBS mixer creates composite video from luma and chroma. Like the MAX9508, the MAX9512's outputs can be dc-coupled to up to two video loads to ground, or ac-coupled to one video load.

To provide additional operational protection, the MAX9508/MAX9512 are offered in the -40°C to +125°C automotive temperature range. The price for the MAX9508/MAX9512 is $0.59 (1000-up, FOB USA). Samples and EV kits are available now.
