Signal Buffers, Repeaters, Splitters FAQ

How does the NB7NPQ1402E2M manage power consumption?

The device utilizes adaptive power management that monitors input signals. If a channel remains idle, it transitions to a low power slumber mode. If no load is detected, it moves to an unplug mode to further minimize current draw.

What are the default settings for the control pins?

The default setting for the equalization (EQA/B), swing (SWA/B), and flat gain (FGA/B) pins is Float (F). The channel enable (EN) pin defaults to Enabled (High), and the receiver detection enable (RXDET_EN) pin also defaults to High.

Can the NB7NPQ1402E2M be used in hot-plug scenarios?

Yes, the device is explicitly designed to be hot-plug capable, allowing for connection and disconnection of peripherals without powering down the system.
