SDI
Ground
Ground
I, SDI
Negative power supply (ground).
Negative power supply (ground).
Serial data true input.
4
SDI
I, SDI
Serial data complement input.
5
V_EE
6
SPI_EN
Ground
I, LVCMOS
Negative power supply (ground).
SPI register access enable. This pin has an internal pulldown.
H = SPI register access mode.
L = Pin mode.
7
SDO1_DISABLE I, LVCMOS Output driver 1 (SDO1, SDO1) disable. This pin has an internal pullup.
H (or no connection) = Output driver 1 is in a high impedance state.
L = Output driver 1 is enabled.
8
AEC+
I/O, Analog AEC loop filter external capacitor (1µF) positive connection (capacitor is optional).
9
AEC-
I/O, Analog AEC loop filter external capacitor (1µF) negative connection (capacitor is optional).
10 CD
O, LVCMOS
Carrier detect.
H = No input signal detected.
L = Input signal detected.
11
MUTE_REF
I, Analog
Mute reference input. Sets the threshold for CD and (with CD tied to MUTE)
determines the maximum cable to be equalized before muting. MUTE_REF may be
either unconnected or connected to ground for normal CD operation.
