SLASE74F May 2015 – September 2016 HD3SS3212
The HD3SS3212 is a generic analog differential passive switch that can work 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 employs adaptive tracking that ensures the channel remains 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 very little added jitter. It consumes <2 mW of power when operational and has a shutdown mode exercisable by OEn pin resulting <20 µW.
The HD3SS3212 has two power modes, active/normal operating mode and standby/shutdown mode. During standby mode, the device consumes very-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 or dynamically controlled to switch between H or L.
HD3SS3212 consumes <2 mW of power when operational and has a shutdown mode exercisable by the EN pin resulting <20 µW.
