Description
Negative power supply (ground).
Serial data true input.
Serial data complement input.
Negative power supply (ground).
AEC loop filter external capacitor (1µF) positive connection.
AEC loop filter external capacitor (1µF) negative connection.
Bypasses equalization and DC restoration when high. No equalization occurs in this mode.
Mute reference. Sets the threshold for CD and (with CD tied to MUTE) determines the maximum
cable to be equalized before muting. MUTE
Negative power supply (ground).
Serial data complement output.
Serial data true output.
Negative power supply (ground).
Positive power supply (+3.3V).
Output mute. To disable the mute function and enable the output, MUTE must be tied to GND or
a low level signal. To force the outputs to a muted state, tie to V
inhibit the output when no input signal is present. MUTE has no function in BYPASS mode.
Carrier detect. CD is high when no signal is present. CD has no function in BYPASS mode.
Positive power supply (+3.3V).
Connect exposed DAP to negative power supply.
