HD Video Filter/Amps Trim Power

Groomed for set-top boxes and portable equipment, the MAX9652, MAX9653, and MAX9654 triple-channel, high-definition (HD) video-filter amplifiers operate from a single 3.3V supply, rather than the usual 5V. To further save power, they consume 9.5 mA of quiescent current per channel. The MAX9653 and MAX9654 also feature a 12-µA shutdown mode. Handling YPbPr component-video signals, the MAX9652 and MAX9653 employ a fixed passband for HD video while the passband of the MAX9654 is logic selectable between SD and HD. The HD low pass filter on all three devices specifies a ±1 dB passband out to 42 MHz and 50 dB attenuation at 109 MHz. The MAX9654's SD low pass filter sports a ±1dB passband out to 8.5 MHz and 57 dB attenuation at 27 MHz. The MAX9652 is available in an eight-pin SO package and the MAX9653 and MAX9654 are available in 10-pin microMAX packages. Prices start at $0.48 for the MAX9652, $0.50 for the MAX9653, and $0.60 for the MAX9654 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
