SD video filter amplifier
29 April 2009, Design Automation

Maxim’s new MAX9519 is a tiny, low pin-count video filter amplifier for standard-definition (SD) video connections from portable devices to TVs. Packaged in a 1 x 1 mm, 4-bump UCSP, this device features Maxim's proprietary SmartSleep technology, which reduces current consumption to 1 μA in shutdown mode and eliminates the need for external shutdown circuitry.

The MAX9519 employs SmartSleep technology to intelligently manage power consumption with no external intervention from a host processor or microcontroller. SmartSleep circuitry constantly monitors the video input for a valid video signal and the video output for the presence of a load. The device only turns on and enters its full operating mode when it detects both video playback and a live connection to the TV. In shutdown mode, this circuitry disables the filter and output amplifier, reducing power consumption to 1 μA.

Featuring a high-order filter, the IC achieves good attenuation of high-frequency artifacts and noise in the video output signal. The integrated 5th-order filter features ±1 dB passband flatness up to 9 MHz and 48,5 dB attenuation at 27 MHz, ensuring signal integrity in ultra-compact designs.

The MAX9519 operates from a 2,7 V to 3,6 V supply and is fully specified over the -40°C to +125°C temperature range.
