PG100D / PG100DI
The PG100D(I) is a highly integrated Ethernet transceiver compliant with IEEE 802.3 10Base-T, 100Base-TX and 1000Base-T standards. It provides all the physical layer functions needed to transmit and receive Ethernet packets over Category 5E unshielded twisted-pair cable. Using advanced mixed-signal processing, the device implements cross-over detection and auto-correction, polarity correction, adaptive equalization, crosstalk cancellation, echo cancellation and timing recovery — delivering robust transmit and receive performance at all three speeds.

Features & Benefits
Tri-Speed Auto-Negotiation
Fully compatible with 10/100/1000 Mbps, with auto-negotiation and parallel detection for automatic link rate matching
Energy Efficient Ethernet
Compliant with IEEE 802.3az-2010, automatically entering and leaving Low Power Idle (LPI) mode based on link utilization
Wake-on-LAN
Magic packet and wake-up frame detection with notification via the PME_n pin for remote power management
Robust Self-Adaptation
Cross-over detection and auto-correction, automatic polarity correction and baseline wander correction simplify cabling and debugging
Highly Integrated Power
Built-in switching regulator and LDO allow operation from a single 3.3 V rail, reducing external components and BOM cost
Compact Package
40-pin QFN in just 5 mm × 5 mm, ideal for space-constrained embedded and portable designs
Flexible Interrupt
Active-low interrupt (INT_n) on PHY status change removes the need for continuous MDIO polling (shared with PME_n on pin 31)
Industrial Grade Option
The PG100DI industrial version supports -40 °C ~ 85 °C wide-temperature operation for harsh field environments
