7 / 28 page – 7 – CXA2089Q/S 27 (33) SDA — I2C bus signal input VILmax = 1.5V VIHmin = 3.0V VOLmax = 0.4V VCC 4k 27 26 (32) SCL — I2C bus signal input VILmax = 1.5V VIHmin = 3.0V VCC 4k 10k 26 28 (34) DC OUT — Outputs the S2-compatible DC superimposed onto the COUT2 output. The DC is superimposed by connecting this pin to the COUT2 output via a capacitor. Control is performed by the I2C bus. When 0V is output, Q1 is ON and the impedance is 5k Ω. S2 protocol output DC impedance of 10 ± 3k Ω is realized by attaching external resistance of 4.7k Ω. DC OUT (bus) Output DC 0 4.5V 1 0V 2 1.9V 3 4.5V VCC 100 1k 42 42 (48) TRAP1 3.8V Connects trap circuit for subcarrier. VCC 4k 28k 1k Q1 28 35 (41) MUTE — Audio signal output mute. Mute OFF at 1.5V or less Mute ON at 2.5V or more Mute OFF when open VCC 147 28k 72k 35 37 (43) BIAS 4.5V Internal reference bias (Vcc/2). Connects to GND via a capacitor.
