Device Address Set Input. Connect DEV_ADDR to GNDVID, VVID, SDA or SCL. See Table 3.
Interrupt Output. This is an open-drain output that pulls down to GNDVID to indicate a change in the
VCR slow-switching input, the activity status of the composite video inputs, or the load status of the
composite video outputs.
Audio Supply. Connect to a 3.3V supply. Bypass with a 10µF aluminum electrolytic capacitor in
parallel with a 0.1µF ceramic capacitor to EP.
Charge-Pump Flying Capacitor Positive Terminal. Connect a 1µF capacitor from C1P to C1N.
Charge-Pump Flying Capacitor Negative Terminal. Connect a 1µF capacitor from C1P to C1N.
Charge-Pump Negative Power Supply. Bypass CPVSS with a 1µF ceramic capacitor in parallel with a
1µF ceramic capacitor to EP.
