I
EN_[A:D] is the enable pin with internal 50KΩ pull up resistor. A LVCMOS high
provides normal operation. A LVCMOS low selects a low power down mode.

K1
EN_CLK
I
Enable output clock pin with internal 50kΩ pull up resistor. When EN_CLK is
LVCMOS high level, the clock output operates normally. When EN_CLK = low,
the clock outputs are turned off for power savings. A clock is not required by the
data channels for operation.
A1, A2, B2, C2
SD_x
N/A
Signal detected, channels A, B, C, D. Indicated a valid signal level on the channels
input pin pair when active high. When low, SD indicates the input signal level is
below the signal detect threshold level.
