SCART switch meets European STB needs

Seeking to address the needs of European set top box (stb) designers, Maxim's latest switches perform SCART video functions and meet European energy-efficiency requirements.

The MAX9655 and MAX9656 devices integrate the filtering, switching, and amplification necessary to cater for RGB and composite-video signals. The reconstruction filters used in both devices suit standard-definition signals, with 1dB passband flatness out to 9.5MHz and 47dB attenuation at 27MHz.

These devices operate from a single 3.3V supply and draw minimal quiescent current, according to Maxim. The MAX9656 enables users to select whether the composite signal sent to the VCR originates from the television SCART input or the encoder. This device has an additional power saving feature in the guise of a low-power shutdown mode that consumes only 35microamps.

The MAX9655 is available in a 16pin QSOP package, and the MAX9656 is available in a 20pin QSOP package. Both devices are specified over the “40oC to +125oC automotive temperature range.
