Detailed Description

Specialized IC in the Integrated Circuits (ICs) category. Part of the well-known 88E1111 family used widely as a single-port Gigabit Ethernet PHY/transceiver for 10/100/1000BASE-T copper links. Typical digital host interfaces include RGMII/GMII/MII. Suffix indicators often denote package, RoHS status, and temperature grade; the “I” commonly indicates an industrial temperature range. Supplied quantity listed: 2800 units. Date code: 21+ (recent production lot). For exact mechanical outline, pinout, and electrical limits, refer to the datasheet on this page.

Key Features

10/100/1000BASE-T copper PHY, IEEE 802.3 compliant

Auto-negotiation and auto MDI/MDI-X for easy network hookup

RGMII/GMII/MII host interface options (typical for this family)

Integrated DSP for echo, NEXT, and FEXT cancellation to maintain link quality

Cable diagnostics and link quality monitoring

Low-power modes and Energy-Efficient Ethernet support on many variants

LED pins for link/activity/speed indication

Industrial temperature option indicated by “I” suffix (verify in datasheet)

RoHS/lead-free variant (suffix-dependent; confirm in datasheet)

Key Advantages

Proven interoperability with a wide range of MACs and switches

Simple board routing using standard RGMII/GMII/MII interfaces

Robust link over 100 m Cat5e/Cat6 copper cables

Auto MDI/MDI-X reduces design complexity and user setup errors

Flexible LED and strap options for configuration without firmware

Mature ecosystem and reference designs shorten time to market

Packaging

Package/case code provided: 869 (use the datasheet and reel/tray label to map this code to the exact mechanical package)

Typical for this family: plastic encapsulated IC package, lead-free, moisture-sensitive (MSL level per datasheet)

Shipment format: tape-and-reel or tray depending on order option; confirm at order

Pin configuration: multi-interface PHY pins include MDI pairs (RX/TX), RGMII/GMII/MII, MDIO/MDC, LED outputs, reset/strap pins, crystal/clock pins, and power/ground (see datasheet’s pin map)

Thermal characteristics: industrial temperature option commonly -40°C to +85°C ambient; follow datasheet junction/thermal resistance data and use good copper pour for heat spreading

Electrical properties (family-typical): I/O rails around 3.3 V; core rails often 2.5 V and/or 1.8 V (some variants integrate regulators). Exact voltages, currents, and tolerances must be taken from the datasheet

Lifecycle

Current market status for this specific suffix can vary by region and date code. Not flagged as last-time-buy in our latest checks, but lifecycle status is subject to change

If you need second-source or alternatives, consider:

- Microchip KSZ9031RNX (Gigabit PHY, RGMII)

- Microchip KSZ9131RNX (Gigabit PHY, RGMII, low power)

- Texas Instruments DP83867IR/CR (Gigabit PHY, RGMII)

- Texas Instruments DP83822I (10/100 PHY if 1G not required)

- Realtek RTL8211 series (e.g., RTL8211E/RTL8211F, Gigabit PHY)

- Broadcom BCM54612/BCM54610 (Gigabit PHY, availability varies)

Always verify pinout, voltage rails, magnetics requirements, strap options, and register set before substituting
