Pin Configuration and Description

Pin

Name

Description

1

TIA INPUT A

Input to the TIA stage of the receiver

2

BIAS1

Biasing for the first stage. The current flowing through this pin is used to control the biasing for

the first stage amplifier

3

NC

Not Connected

4

BIAS1

Biasing for the first stage. The current flowing through this pin is used to control the biasing for

the first stage amplifier
