QUICK TAKE
Maxim Integrated Products has introduced the MAX9508/ MAX9512, the world's
first analog standard-definition video filters equipped with the company's innovative
SmartSleep technology. MAXIM INTEGRATED PRODUCTS CORP., Sunnyvale, CA.
(800) 998-8800.
MORE INFO
The 4-channel MAX9508 and MAX9512 video filter amplifiers substantially
reduce power consumption by shutting down the filters and amplifiers of the
unused channels. The MAX9508 provides bidirectional video support and contains
three reconstruction filters, four video amplifiers, and a pull-down switch
at one of two CVBS (composite video) outputs. An internal switch can be used
as a 2:1 multiplexer to select between two input sources. This switch can also
control the bidirectional video signals at the CVBS connections without needing
separate switches or relays. The two CVBS outputs can be dc-coupled and drive
up to two video loads to ground, or accoupled to one video load. The MAX9512
adds a Y/C mixer and is designed specifically for portable media players. The
Y/Cto-CVBS mixer creates composite video from luma and chroma signals. Both
devices are available in the -40°C to +125°C automotive temperature
range.

WHY ARE THESE DEVICES IMPORTANT?
The new SmartSleep technique
employed by the MAX 9508 and MAX9512 intelligently controls power consumption
by turning on the device only when the video input signal and the output load
are detected. Traditional devices cannot selectively turn on or off based on
the status of the input or output loads. Nor can those devices intelligently
decide when to turn on or off.
MORE ABOUT SmartSleep
Depending on the presence of the input signal and
the output load, the SmartSleep function places individual video channels in
one of three power-consumption modes: 1) Standby Mode, 2) Active-Detect Mode
and 3) Full-Operation Mode
Standby Mode: When there is no active video input signal, the device is placed into the standby mode, and the device reduces the supply current to 7 µA.
Active-Detect Mode: When there is an input sync signal, the channel is placed into an active-detect mode and starts sensing the presence of an output load. In this mode, the device consumes just 17 µA.
Full-Operation Mode: When there is an input signal and an output load, the device is placed into the full-operation mode. It selectively activates the video filter and the amplifier of an output channel with an attached load. In this mode, the device consumes 3.3 mA per channel, plus the output load current.
