3.3 Ethernet Sub‑System
| Component | Role | Notable Values | |-----------|------|----------------| | DP83848 PHY | 10/100 Mbps Ethernet transceiver (RMII) | Integrated 50 Ω termination resistors; internal PLL 25 MHz. | | Magnetics | 10/100 Mbps isolation transformer (LAN8720 style) | 75 Ω primary, 100 Ω secondary; includes common‑mode choke. | | RJ45 Connector | 8‑P8C RJ45 (with integrated magnetics) | LED1/LED2 tied to PHY’s LINK/ACT pins (via 2.2 kΩ). | | MDIO/ MDC | Management interface | Pull‑up 4.7 kΩ on MDC; MDIO open‑drain with 1 kΩ pull‑up. |
The MBX252 schematic can be divided into several key sections:
- Signal Tracing: Boardview tells you where a resistor is. The schematic tells you what that resistor does (e.g., pull-up for the SMBus clock).
- Voltage Ladders: The MBX252 uses complex voltage divider networks to enable secondary supplies (like +1.5V_ICH). You cannot measure these without the schematic.
