Key Differentiators
- Higher data rate (50 Mbps) compared to many alternatives (vs MAX3485E)
- Wider supply range (3.0 V to 5.5 V) with VIO logic supply (vs SN65HVD3082E)
- IEC 61000-4-2 ESD protection (±12 kV) on bus pins (vs MAX3485E)
Design Notes
For high-speed RS-485 communication at 50 Mbps, PCB layout is critical. Keep the bus lines (A and B) as short as possible and use controlled impedance traces (typically 120 Ω differential). Place the termination resistor (120 Ω) at both ends of the bus. Ensure a solid ground plane and minimize vias to reduce signal reflections and EMI.
Decouple the VCC pin with a 0.1 µF ceramic capacitor placed as close to the pin as possible. If the VIO pin is used, add a 0.1 µF capacitor to the VIO rail as well. For noisy industrial environments, consider adding a ferrite bead in series with VCC to filter high-frequency noise.
Ensure the DE and RE pins are not left floating; they should be tied to appropriate logic levels to avoid unintended driver activation. When using half-duplex, implement proper bus arbitration to prevent driver contention. Also, verify that the VIO voltage does not exceed VCC to avoid latch-up.
