Schematische Darstellung der Lösung
1. PHY
Entspricht der 1000BASE-T1 IEEE 802.3bp-Spezifikation
Entspricht der 100BASE-T1 IEEE 802.3bw-Spezifikation
RGMII unterstützt mehrere Spannungsniveaus, einschließlich 3,3/2,5/1,8/1,5 V
Integrierter MDI-Schnittstellen-Abschlusswiderstand zur Eliminierung passiver Komponenten
Unterstützt Auto-negotiation
Unterstützt die Kompensation der Basisliniendrift (BLW).
Unterstützt Interrupt-Funktionalität
Unterstützt Wake-up on Network (WoL)-Funktionalität
Adaptive Entzerrung und Echounterdrückung
Automatische Polaritätskorrektur
Netzwerkstatusanzeige
Unterstützt IEEE 1588v1/v2 und 802.1AS
Extrem geringer Stromverbrauch
Paket: 40-Pin 6mm×6mm QFN

VDD_HV_B: Die Stromversorgung des Ethernet-Moduls beträgt 3 V und ist an die VDD-Stromdomäne angeschlossen
TX_EN: Sendefreigabesignal
SMI: Serielle Verwaltungsschnittstelle, einschließlich MDC- und MDIO-Signalleitungen.
TXD[1:0]: Datenübertragungssignal, ein 2-Bit-Datensignal.
RXD[1:0]: Data receive signal, a 2-bit data signal. The RMII interface exchanges 2-bit data signals TXD[1:0] and RXD[1:0], and transmit and receive signals are synchronized with REF_CLK (shared reference clock).
RX_ER: Receive error signal. This signal must be held for one or more cycles (RX_CLK) to indicate to the MAC sublayer that an error has been detected somewhere in the frame.
RX_DV: Receive data valid signal. This signal indicates that the PHY is currently receiving a recovered and decoded half-byte for RMII reception.
TX_CLK: Continuous clock signal, which provides the reference timing for TX data transmission. The nominal frequency is 5MHz for a speed of 10Mbit/s and 50MHz for a speed of 100 Mbit/s. Currently, the S32K344 board uses an external crystal oscillator to provide a 50MHz clock source for 100Mbit/s communication.

2. LAN-Transformator
Voohu introduces a new type of chip network transformer (Chip Lan) with leading fully automated production. It adopts an H+I structure and a fully automated production mode, breaking through the traditional toroidal wound transformer and inductor design schemes to achieve large-scale, fully automated production. The product complies with EU RoHS 2.0 standards and is compatible with products from major global PHY chip suppliers.

The 100/1000/2.5G/5G/10GBASE-T new chip network transformer complies with the relevant standards of IEEE 802.3 wired LAN. Its advantages of small size, high voltage withstand, wide temperature compatibility, and low cost make it widely used in network communication, consumer electronics, and other fields.
