8 Detailed Description

8.1 Overview

The HD3SS3202 is a generic analog differential passive switch that can works for any high-speed interface

applications requiring a common mode voltage range of 0 to 2 V and differential signaling with differential

amplitude up to 1800 mVpp. It uses adaptive tracking to ensures the channel remain unchanged for the entire

common mode voltage range.

Excellent dynamic characteristics of the device allow high-speed switching with minimum attenuation to the

signal eye diagram with little added jitter. It consumes < 1.65 mW (typ) of power when operational and has a

shutdown mode exercisable by OEn pin resulting < .02 µW (typical).

8.3.1 Output Enable and Power Savings

The HD3SS3202 has two power modes, active/normal operating mode and standby/shutdown mode. During

standby mode, the device consumes little current to save the maximum power. To enter standby mode, the OEn

control pin is pulled high through a resistor and must remain high. For active/normal operation, the OEn control

pin should be pulled low to GND.

HD3SS3202 consumes < 1.65 mW (typ) of power when operational and has a shutdown mode exercisable by

the OEn pin resulting < .02 µW (typ).
