CS-BGA BALL

AEC+

E2

I/O, Analog

AEC loop filter external capacitor (1-µF) positive connection.

AEC-

E3

I/O, Analog

AEC loop filter external capacitor (1-µF) negative connection.

Bypasses equalization and DC restoration when high. No equalization occurs in this

BYPASS

mode. This pin does not have an internal pulldown. If the bypass function is not used,

this pin requires an external pulldown resistor to disable bypass.

Carrier detect. CD is high when no signal is present. CD has no function in BYPASS

Output mute. To disable the mute function and enable the output, MUTE must be tied

function in BYPASS mode.

Mute reference. Sets the threshold for CD and (with CD tied to MUTE) determines the
