  • The MAX9655/MAX9656 are low-power switches that support the video portion of dual-SCART, set-top-box designs. The MAX9656 also allows users to select the source of the composite-video signal being sent to the VCR.
  • When the functionality of a fully integrated dual-SCART IC is not required, these devices enable customers to implement a simple, low-cost solution.
  • The MAX9655/MAX9656 integrate the video filtering, switching, and amplification portions of a dual-SCART solution. This integration allows users to avoid the complexity of a fully discrete solution while still minimizing cost.
  • The MAX9655/MAX9656 can be used to economically support the video portion of dual-SCART set-top boxes.

SUNNYVALE, CA — Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX9655/MAX9656* low-power switches that support the video portion of dual-SCART, set-top-box designs. These devices integrate the filtering, switching, and amplification necessary for RGB and composite-video signals in set-top boxes. The reconstruction filters on both devices are optimized for standard-definition signals and typically have ±1dB passband flatness out to 9.5MHz and 47dB attenuation at 27MHz. The MAX9656 also allows users to select whether the composite signal sent to the VCR originates from the television SCART input or the encoder. Integrating only SCART video functions, the MAX9655/MAX9656 allow users to avoid the complexity of a fully discrete solution, while still minimizing the cost of the set-top-box design.

Designed to meet the energy-efficiency requirements of European set-top boxes, the MAX9655/MAX9656 operate from a single 3.3V supply and draw very little quiescent current. To further save power, the MAX9656 offers a low-power shutdown mode in which it consumes only 35µA.

The MAX9655 is available in a 16-pin QSOP package, and the MAX9656 is available in a 20-pin QSOP package. Both devices are fully specified over the -40°C to +125°C automotive temperature range. Prices start at $0.50 (1000-up, FOB USA).
