CXA2126Q
Audio/Video Switch with Electronic Volume for 2 Scart
Description
The CXA2126Q is an I2C programmable audio, video
switch designed primarily for set top box applications. It
interfaces from digital encoder sources to TV and VCR
scart connectors.
Features
• 2 scart independent audio/video switching (TV, VCR)
• Compatible with 3 scart Audio/Video switch,
CXA2125Q
• 0 to –63dB volume control with click noise reduction
• 3 stereo audio inputs
• I2C control
• Scart Function Switching input and output
• Scart Fast Blanking for OSD
• Mono switchable to stereo on TV and VCR outputs
• On-chip +12V to +9V voltage regulator
• Logic output
• Selectable +6dB, +12dB gain on TV output
• RGB input on VCR scart
