Sunnyvale, Calif.Maxim Integrated Products has introduced the MAX9598, a +3.3V dual SCART chip for set-top boxes and A/V receivers that have two SCART connectors.
The MAX9598 uses power-saving, “green” technology to achieve low power consumption. Additionally, the MAX9598 integrates the company's patented DirectDrive technology to prevent click-and-pop noise and eliminate the need for costly AC-coupling capacitors on the audio outputs. The MAX9598 is available in a space-saving, 6mm x 6mm TQFN package.
The MAX9598 is a switch matrix that eases routing of audio and video signals between an MPEG decompression chip and two external SCART connectors. The A/V channels feature input-source-selection multiplexers, input buffers, and output buffers for routing all inputs to selected outputs. The MAX9598 integrates standard-definition video filters on all video encoder inputs, and all audio drivers deliver a full-scale (2.0Vrms, min) output. The device also integrates input-video-signal and video-load detection circuitry. Controlled through an I²C-compatible interface, the MAX9598 fully complies with the EN50049-1 SCART standard.
The MAX9598 operates audio and video circuitry from +3.3V and only requires +12V for the slow-switching signal. An internal charge pump inverts the +3.3V supply and generates a -3.3V supply, thereby providing sufficient voltage swing to support 2.0Vrms audio. It consumes 70mW of quiescent power.
Pricing: Starts at $1.50 (1000-up, FOB USA).
