Key Differentiators
- Small 40-pin WQFN package (vs DP83848CVVX)
- Industrial temperature range (vs DP83848CVVX)
- Pin-compatible with DP83848HSQ/NOPB (vs DP83848HSQ/NOPB)
Design Notes
For optimal signal integrity, route the differential pairs (TX+/-, RX+/-) with controlled impedance of 100 ohms. Keep the traces short and avoid vias where possible. Place the magnetics (transformer) close to the PHY to minimize stub length. Use a solid ground plane beneath the PHY and magnetics to reduce EMI.
Decouple the 3.3V supply with a 10uF bulk capacitor and 0.1uF ceramic capacitor placed close to the VDD pins. The DP83848KSQ/NOPB requires a clean supply to maintain signal integrity. Consider using a ferrite bead to isolate the PHY supply from other digital noise.
Ensure the MDIO interface is properly terminated with pull-up resistors on MDIO and MDC lines. Incorrect termination can cause management interface failures. Also, verify the clock source (25 MHz crystal or oscillator) meets the jitter requirements specified in the datasheet to avoid link instability.
Compliance Information
