MAX4399CTK+

Audio Special Purpose Overview

The MAX4399CTK+ is an audio/video switch IC designed for digital set-top box applications, providing routing from MPEG decoder sources to TV, VCR, and AUX SCART connectors. It operates on standard +5V and +12V single supplies within a commercial temperature range of 0°C to +70°C. The device features a fast-mode I²C-compatible interface supporting data rates up to 400kbps. Key electrical specifications include a 27MHz large-signal bandwidth (-3dB) for video drivers, a low -86dB video signal-to-noise ratio, and programmable audio gain control ranging from -56dB to +6dB in 2dB steps.

Audio Special Purpose Feature Summary

• Supports three SCART connectors with full CVBS loop-through on the AUX port
• Features clickless audio switching and programmable volume control for TV audio outputs
• Includes an on-chip luma/chroma mixer and external RLC trap filter for RF modulator drive
• Provides RGB output gain programming of +6dB ±1dB and fixed +6dB gain for other video outputs

Audio Special Purpose Applications

• Satellite Set-Top Boxes
• Cable Set-Top Boxes
• Terrestrial Set-Top Boxes
• Digital Television (DTV)
• DVD+R/W Players

Audio Special Purpose Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm package integrity for the 68-TQFN form factor upon receipt. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing design implementations.

Audio Special Purpose Selection Notes

Select this component when designing systems requiring simultaneous management of three SCART interfaces. Ensure power supply rails are stable at +5V and +12V. Verify that the PCB layout accommodates the 68-pin thin QFN package dimensions and thermal requirements for continuous operation within the specified temperature range.
