Table 1. Pin Descriptions

Pin No.

Name

Description

1

Negative power supply (ground).

2

SDI

Serial data true input.

3

SDI

Serial data complement input.

4

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

9

Negative power supply (ground).

10

SDO

Serial data complement output.

11

SDO

Serial data true output.

12

Negative power supply (ground).

13

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

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

Positive power supply (+3.3V).

DAP

Connect exposed DAP to negative power supply.
