PI2EQX4432DZDE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX4432DZDE is a low-power, PCI Express compliant signal Re-Driver designed for two high-speed lanes operating at data rates up to 2.5 Gbps per lane. It features programmable equalization to reduce Inter-Symbol Interference (ISI) and includes adjustable output de-emphasis set at -3.5dB. The device utilizes 100-Ohm differential CML I/Os and incorporates input signal level detection with output squelch on all channels. It operates within a VDD range of 1.8V ±0.1V, consumes approximately 100mW per channel, and supports a standby power-down mode. The component is housed in a 48-contact TQFN package.

Signal Buffers, Repeaters, Splitters Feature Summary

• Low power consumption with dedicated standby mode accessible via independent channel enable pins
• Flow-through pinout architecture supporting direct routing between Protocol ASICs and switch fabrics

Signal Buffers, Repeaters, Splitters Applications

• PCI Express signal re-conditioning between Protocol ASICs and switch fabrics
• Signal extension across backplanes in server and storage systems
• Extending signals across distant data pathways on user platforms requiring compliance with PCI Express standards

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging variations. The 'E' suffix indicates Pb-free and Green material composition. Confirm whether the 'X' suffix is required for tape and reel delivery formats. Ensure the selected variant matches the thermal and mechanical requirements for the intended PCB layout.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing interfaces requiring PCI Express Gen-I compliance at 2.5 Gbps. The device is suitable for applications needing adjustable equalization to compensate for media-induced losses. Consider the 1.8V supply requirement and the availability of configuration pins for setting equalization and de-emphasis levels. Verify that the 48-contact TQFN package fits the available board space and thermal dissipation constraints.
