ADM3067EBRMZ - 50Mbps Full Duplex RS-485 Transceiver | Analog Devices
MPN： ADM3067EBRMZ ✓ 啟用中ADM3067EBRMZ 概覽
RS-485 transceivers are essential components in industrial automation, building control, and instrumentation systems, enabling reliable differential data transmission over long cable runs. They convert TTL-level signals to balanced differential signals and vice versa, providing noise immunity and supporting multi-drop networks. The ADM3067E family includes both half-duplex and full-duplex variants, with the ADM3067E being a full-duplex device that allows simultaneous transmit and receive operations.
Key features of the ADM3067EBRMZ include a wide supply voltage range, high-speed 50 Mbps data rate, and full fail-safe receiver operation. The receiver is fail-safe for open, shorted, and idle bus conditions, ensuring a known output state when the bus is not actively driven. The device also supports hot swap with glitch-free power-up and power-down, preventing spurious transitions on the bus during insertion or removal. Additionally, the transceiver is PROFIBUS compliant at VCC ≥ 4.5 V, making it ideal for industrial PROFIBUS networks.
From a technical perspective, the ADM3067EBRMZ integrates a differential driver and receiver with a 1/1 transceiver configuration. The driver output is short-circuit protected, and the receiver has a wide common-mode input range, allowing operation in noisy environments. The device features a thermal shutdown protection mechanism to prevent damage from excessive power dissipation. The ESD protection on the bus pins is rated at ±12 kV IEC 61000-4-2 contact discharge, providing robust protection against electrostatic discharge events.
Typical applications for the ADM3067EBRMZ include industrial automation, building automation, HVAC systems, and motor control. Its high-speed capability makes it suitable for applications requiring fast data throughput, such as PROFIBUS DP networks. The full-duplex operation enables simultaneous bidirectional communication, which is beneficial in point-to-point and multi-drop configurations.
When designing with the ADM3067EBRMZ, it is important to ensure proper termination at both ends of the bus to minimize signal reflections. The device's fail-safe receiver feature simplifies bus idle handling, but external biasing may still be required in some configurations. Additionally, the supply voltage should be decoupled with a 0.1 µF capacitor close to the VCC pin to ensure stable operation.

設計說明
Place a 0.1 µF decoupling capacitor as close as possible to the VCC pin (pin 11) and ground. Use a 10 µF 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 Ω) 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.
