Description
Serial data true input.
Serial data complement input.
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_REF may
be either unconnected or connected to ground for maximum equalization.
Serial data complement output.
Serial data true output.
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_CC. CD may be tied to this pin to 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).
Negative power supply (ground).
No connect.
