PIN DESCRIPTIONS

WQFN Pin

CS-BGA Ball

Name

Description

2

C1

SDI

Serial data true input.

3

D1

SDI

Serial data complement input.

5

E2

AEC+

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

6

E3

AEC-

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

7

D3

BYPASS

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

mode.

8

E4

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

or connected to ground for maximum equalization.

10

D5

SDO

Serial data complement output.

11

C5

SDO

Serial data true output.

14

B3

MUTE

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

be tied to this pin to inhibit the output when no input signal is present. MUTE has no

function in BYPASS mode.

15

A2

CD

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

mode.

13, 16
