Key Differentiators
- Higher data rate (50 Mbps) compared to many alternatives (vs ISL3177E)
- Wider operating temperature range (-40Β°C to +125Β°C) (vs MAX3077E)
- PROFIBUS compliance at VCC β₯ 4.5 V (vs MAX3077E)
Design Notes
Place a 0.1 Β΅F decoupling capacitor as close as possible to the VCC pin (pin 11) and ground. Use a 10 Β΅F bulk capacitor on the supply rail if the transceiver is located far from the power source. Ensure a solid ground plane under the device to minimize noise and improve ESD performance.
Route the differential bus lines (A, B, Y, Z) as a twisted pair or closely coupled traces to maintain characteristic impedance. Keep the traces away from high-noise sources such as switching regulators. Add series termination resistors (e.g., 120 Ξ©) at both ends of the bus to match the cable impedance and reduce reflections.
Do not exceed the absolute maximum ratings for supply voltage or bus voltage. Ensure the bus is properly terminated to avoid signal integrity issues. When using hot swap, ensure the bus is not actively driven during power-up to prevent glitches. Verify that the receiver fail-safe feature is compatible with your bus biasing scheme.
