Pin Descriptions – Pin Mode (non-SPI) / SPI_EN = GND
Pin Name I/O, Type Description
1 V
EE
Ground Negative power supply (ground).
2 V
EE
Ground Negative power supply (ground).
3 SDI I, SDI Serial data true input.
4 SDI I, SDI Serial data complement input.
5 V
EE
Ground Negative power supply (ground)
6 SPI_EN I, LVCMOS 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 BYPASS I, LVCMOS Equalization bypass. This pin has an internal pulldown.
H = Equalization is bypassed (no equalization occurs).
L = Normal operation.
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.
12 V

Ground Negative power supply (ground).
13 V
EE
Ground Negative power supply (ground).
14 SDO0 O, LVDS Serial data output 0 complement.
15 SDO0 O, LVDS Serial data output 0 true.
16 V
EE
Ground Negative power supply (ground).
17 SDO1 O, LVDS Serial data output 1 complement.
18 SDO1 O, LVDS Serial data output 1 true
