PI3L2500ZHEX

Analog Switches - Special Purpose Overview

The PI3L2500ZHEX is an 8-channel, bidirectional 2:1 multiplexer/demultiplexer LAN switch designed for Gigabit Ethernet applications. It operates within a VDD range of +3.0V to +3.6V and features a 3GHz bandwidth with propagation delay under 250ps. The device supports 1000/2500/10000 Base-T standards, offering low bit-to-bit skew of 200ps and very low crosstalk of -53dB at 400MHz. It includes power-down functionality via the PD pin and status indicator LEDs switched with Ethernet pairs. Packaged in a 42-contact TQFN (3.5 x 9mm) with enhanced ESD protection.

Analog Switches - Special Purpose Feature Summary

• Bidirectional switching between dual physical layer devices and one interface connector, or one controller to dual connectors
• Supports 1000/2500/10000 Mbit Ethernet routing with minimal signal attenuation
• Integrated power-down mode eliminates external power switches during standby
• Status indicator LEDs switched directly with Ethernet pairs

Analog Switches - Special Purpose Applications

• Dual Physical Layer Device sharing to one interface connector
• One controller to dual connectors for docking
• Routes signals for 1000/2500/10000 Mbit Ethernet

Analog Switches - Special Purpose Procurement Notes

Verify the part number suffix 'X' indicates tape and reel packaging configuration. Confirm RoHS compliance and lead-free status against current environmental directives. Ensure the 42-contact TQFN package dimensions match the design footprint requirements. Check for halogen and antimony-free certification if required by specific manufacturing standards.

Analog Switches - Special Purpose Selection Notes

Select this component for high-speed LAN switching where low skew and isolation are critical. The 3GHz bandwidth ensures compatibility with 10Gbps Ethernet standards. Verify that the operating voltage range of 3.0V to 3.6V aligns with the system power supply. Consider the integrated power-down feature for mobile applications requiring standby modes without external components.

Analog Switches - Special Purpose Part Context

The PI3L2500 series serves as a replacement for mechanical relays in low-voltage LAN applications. It interfaces physical layers over CAT 5 or CAT 6 unshielded twisted pair cables through isolation transformers. The device provides industry-leading performance metrics for signal integrity in enterprise network environments.
