CXA2089Q/S
S2-Compatible 5-Input 2-Output Audio/Video Switch
Description
The CXA2089Q/S is a 5-input, 2-output audio/video
switch featuring I2C bus compatibility for TVs. This IC
has input pins that are compatible with S2 protocol.
CXA2089Q
48 pin QFP (Plastic)
CXA2089S
48 pin SDIP (Plastic)
Features
• 3 inputs that are compatible with S2 protocol
• Serial control with I2C bus
• 5 inputs, 2 outputs
• The desired inputs can be selected independently
for each of the 2 outputs
• Wide band video amplifier (20MHz, –3dB)
• Y/C MIX circuit
• Slave address can be changed (90H/92H)
• Audio muting from external pin
• High impedance maintained by I2C bus lines (SDA,
SCL) even when power is OFF
• Wide audio dynamic range (3Vrms typ.)
