PINTYPE(1)DESCRIPTION
NAMELMK1D1208I
DIFFERENTIAL/SINGLE-ENDED CLOCK INPUT
IN0_P, IN0_N12, 13IPrimary: Differential input pair or single-ended input
IN1_P, IN1_N8, 9ISecondary: Differential input pair or single-ended input.
I2C PROGRAMMING
SDA5I/OI2C data
SCL6II2C clock
IDX015I,S,PUI2C address bit[0]. This is a 2-level input that is decoded in conjunction with pin 15 to set the I2C address. It has internal 670-kΩ pullup.
IDX116I,S, PUI2C address bit[1]. This is a 2-level input that is decoded in conjunction with pin 16 to set the I2C address. It has internal 670-kΩ pullup.
BIAS VOLTAGE OUTPUT
VAC_REF0, VAC_REF114, 10OBias voltage output for capacitive coupled inputs. If used, TI recommends using a 0.1-µF capacitor to GND on this pin.
