Description
Negative power supply (ground).
Serial data true input.
Serial data complement input.
SPI register access enable. This pin has an internal pulldown.
H = SPI register access mode.
L = Pin mode.
AEC loop filter external capacitor (1µF) positive connection (capacitor is optional).
AEC loop filter external capacitor (1µF) negative connection (capacitor is optional).
Carrier detect.
H = No input signal detected.
L = Input signal detected.
Mute reference input. Sets the threshold for CD and (with CD tied to MUTE)
determines the maximum cable to be equalized before muting. MUTE
either unconnected or connected to ground for normal CD operation.
SPI slave select. This pin has an internal pullup.
Serial data complement output.
Serial data true output.
SPI Master Input / Slave Output. LMH0394 control data transmit.
Positive power supply (+2.5V).
SPI serial clock input. This pin has an internal pulldown.
SPI Master Output / Slave Input. LMH0394 control data receive. This pin has an
internal pulldown.
Positive power supply (+2.5V).
Connect exposed DAP to negative power supply (ground).
