Description
Negative power supply (ground).
Negative power supply (ground).
Serial data true input.
Serial data complement input.
Negative power supply (ground)
SPI register access enable. This pin has an internal pulldown.
H = SPI register access mode.
L = Pin mode.
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.
AEC loop filter external capacitor (1µF) positive connection (capacitor is optional).
AEC loop filter external capacitor (1µF) negative connection (capacitor is optional).
Equalization bypass. This pin has an internal pulldown.
H = Equalization is bypassed (no equalization occurs).
L = Normal operation.
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.
Negative power supply (ground).
Negative power supply (ground).
Serial data output 0 complement.
Serial data output 0 true.
Negative power supply (ground).
Serial data output 1 complement.
Serial data output 1 true
Auto Sleep. AUTO SLEEP has precedence over MUTE and BYPASS. This pin
has an internal pullup.
H = When no input signal is detected, the device will power down and the outputs
will be in a high impedance state.
L = Device will not enter auto power down.
Positive power supply (+2.5V).
Output mute. CD may be tied to this pin to inhibit the output when no input signal
is present. MUTE has precedence over BYPASS. This pin has an internal
pulldown.
H = Outputs are forced to a constant logic high state.
L = Outputs are enabled.
Carrier detect.
H = No input signal detected.
L = Input signal detected.
Negative power supply (ground).
Positive power supply (+2.5V).
Connect exposed DAP to negative power supply (ground).
