PIN DESCRIPTIONS – SPI Mode / SPI_EN = V
CC
Pin Name I/O, Type Description
1 V
EE
Ground Negative power supply (ground).
2 SDI I, SDI Serial data true input.
3 SDI I, SDI Serial data complement input.
4 SPI_EN I, LVCMOS SPI register access enable. This pin has an internal pulldown.
H = SPI register access mode.
L = Pin mode.
5 AEC+ I/O, Analog AEC loop filter external capacitor (1µF) positive connection (capacitor is optional).
6 AEC- I/O, Analog AEC loop filter external capacitor (1µF) negative connection (capacitor is optional).
7 CD O, LVCMOS Carrier detect.
H = No input signal detected.
L = Input signal detected.
8 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.
9 SS (SPI) I, LVCMOS SPI slave select. This pin has an internal pullup.
10 SDO O, LVDS Serial data complement output.
11 SDO O, LVDS Serial data true output.
12 MISO (SPI) O, LVCMOS SPI Master Input / Slave Output. LMH0394 control data transmit.
13 V
CC
Power Positive power supply (+2.5V).
14 SCK (SPI) I, LVCMOS SPI serial clock input.
15 MOSI (SPI) I, LVCMOS SPI Master Output / Slave Input. LMH0394 control data receive. This pin has an internal
pulldown.
16 V
CC
Power Positive power supply (+2.5V).
DAP V
EE
Ground Connect exposed DAP to negative power supply (ground).
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
