PI2EQX4432DZDEX

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX4432DZDE is a low-power PCI Express compliant signal Re-Driver designed to support two high-speed lanes operating at data rates up to 2.5 Gbps per lane. It features adjustable receiver equalization and output de-emphasis set to -3.5dB to optimize signal integrity by reducing inter-symbol interference across backplanes or distant pathways. The device includes input signal level detection and output squelch on all channels, with 100-Ohm differential CML I/Os. It operates within a VDD range of 1.8V ±0.1V, consumes 100mW per channel in active mode, and supports a standby power-down state. Latency from input to output is typically 2.0 ns.

• Flow-through pinout architecture supporting direct connection between Protocol ASIC and switch fabric

Signal Buffers, Repeaters, Splitters Applications

• PCI Express signal re-driving across backplanes
• Extending signals across distant data pathways on platform designs
• Connecting Protocol ASICs to switch fabrics

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ZDE confirms the 48-contact TQFN package and Pb-free/Green status. Confirm that the 'E' suffix denotes environmental compliance as specified in the manufacturer's documentation. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability for industrial applications.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring PCI Express compliance at 2.5 Gbps speeds. It is suitable for applications needing adjustable equalization to mitigate inter-symbol interference. Consider the 48-contact TQFN package constraints and the requirement for a 1.8V supply voltage during the schematic capture phase.
