TRIPLE SCART AUDIO/VIDEO SWITCH INCLUDES OUTPUT BUFFERS
SUNNYVALE, CA-July 29, 2003-Maxim Integrated Products
(NASDAQ: MXIM) introduces the MAX4399 triple SCART audio/video switch with integrated 150 output buffers. Ideal for digital set-top boxes and DVD+R/W applications, the MAX4399 provides audio and video routing from the digital encoder to the TV, VCR, and AUX SCART connectors.
The TV audio channel features clickless switching and programmable volume control from -56dB to +6dB in 2dB steps. The MAX4399 mixes an auxiliary audio tone into the TV audio channel and the stereo audio signal into a mono audio signal. The device directly drives an external RF modulator with a composite video with blanking and sound (CVBS) signal created by an on-chip luma/chroma (Y/C) mixer.
The MAX4399 operates with standard 5V and 12V single supplies and supports slow and fast switching. All video and audio inputs are AC-coupled. The DC biases of all inputs and output signals are set to predefined levels. All video outputs, including the RF modulator, drive standard 150 loads. Red, green, and blue (RGB) outputs feature 6dB ±1dB programmable gain. All other video outputs have a 6dB fixed gain. The VCR and AUX audio output gains are programmable for -6dB, 0dB, and +6dB.
The MAX4399 triple SCART A/V switch is available in a space-saving 68-pin QFN package and is specified over the commercial temperature range
(-0°C to +70°C). Prices start at $1.95 (100k-up, FOB USA).
