Pin Descriptions
Pin Name Description
1 V
EE
Negative power supply (ground).
2 SDI Serial data true input.
3 SDI Serial data complement input.
4 V
EE
Negative power supply (ground).
5 AEC+ AEC loop filter external capacitor (1µF) positive connection.
6 AEC- AEC loop filter external capacitor (1µF) negative connection.
7 BYPASS Bypasses equalization and DC restoration when high. No equalization occurs in this mode.
8 MUTE
REF
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 unconnected for maximum equalization.
9 V
EE
Negative power supply (ground).
10 SDO Serial data complement output.
11 SDO Serial data true output.
12 V
EE
Negative power supply (ground).
13 V
CC
Positive power supply (+3.3V).
14 MUTE 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.
15 CD Carrier detect. CD is high when no signal is present. CD has no function in BYPASS mode.
16 V
CC
Positive power supply (+3.3V).
DAP V
EE
Connect exposed DAP to negative power supply.
