PI1EQX512AXUAEX

Signal Buffers, Repeaters, Splitters Overview

The PI1EQX512A is a single-port USB 3.0 ReDriver designed for ultra-low-power signal integrity applications. It operates on a single 1.0V supply voltage and supports data rates up to 5.0Gbps. The device features two 100Ω differential CML data I/Os, providing adjustable receiver equalization and pin-configured output de-emphasis to mitigate inter-symbol interference. Key electrical characteristics include an approximate power consumption of ~70mW in active mode. It incorporates automatic receiver detection with a 7.3ms timeout threshold, input signal level detection, and channel-specific squelch functions. The component is housed in an 18-pin TQFN package measuring 2 x 2 mm.

Generic USB redrivers may lack the specific 1.0V operation or integrated receiver detect logic found in this model.

Signal Buffers, Repeaters, Splitters FAQ

How does the PI1EQX512A handle inactive connections?

The device utilizes an automatic receiver detect loop that monitors signal activity. If the detector remains idle for longer than 7.3ms, it transitions the channel to Unplug Mode if no load is detected, or returns to Low Power Slumber Mode due to inactivity.

What type of I/O interfaces does the PI1EQX512A support?

It supports two 100Ω differential CML (Current Mode Logic) data I/O pairs, facilitating connection between the Protocol ASIC and downstream components like switch fabrics or cables.

Is the equalization in the PI1EQX512A programmable?

Yes, the device provides adjustable receiver equalization and pin-configured output emphasis control to optimize performance over different physical mediums and reduce inter-symbol interference.
