Product details

Overview

ADN4650BRWZ-RL7 from Analog Devices is a dual-channel, 5 kV_RMS galvanically isolated LVDS buffer supporting up to 600 Mbps data rates with 4.5 ns max propagation delay, 151 ps peak-to-peak total jitter, and −75 dBc power supply ripple rejection. It integrates iCoupler® technology for drop-in isolation in high-speed analog front-end and data plane interfaces.

For engineers reviewing the ADN4650BRWZ-RL7 datasheet, ADN4650BRWZ-RL7 pinout, ADN4650BRWZ-RL7 application, or ADN4650BRWZ-RL7 equivalent, this device delivers certified reinforced insulation (UL 1577, VDE 0884-17), fail-safe output logic, and dual 2.5 V/3.3 V supply flexibility - critical for industrial AFEs, isolated SPI over LVDS, and high-CMTI timing links.

Technical Context

The ADN4650BRWZ-RL7 implements two independent LVDS isolator channels using capacitive iCoupler® technology, enabling galvanic separation between input and output sides while maintaining TIA/EIA-644-A compliance. Each channel features matched differential receivers and drivers with integrated LDOs accepting 3.0–3.6 V input to generate regulated 2.375–2.625 V supplies.

It provides fail-safe output high behavior only on ADN4651/ADN4652 variants; the ADN4650BRWZ-RL7 does not include fail-safe logic. Its 20-lead SOIC package delivers 5 kV_RMS isolation with 7.8 mm creepage/clearance and >25 kV/μs common-mode transient immunity.

Key Specifications

Parameter	Value and Actual Design Meaning
Isolation Rating	5 kV_RMS for 1 minute - enables reinforced insulation per UL 1577, IEC/CSA 62368-1, and IEC/CSA 60601-1 in medical and industrial systems.
Max Data Rate	600 Mbps - supports high-throughput serial links such as isolated JESD204B/C, camera interfaces, and real-time control buses.
Propagation Delay	4.5 ns maximum - ensures deterministic timing in closed-loop feedback paths and synchronous sampling applications.
Total Jitter (BER 1e−12)	151 ps peak-to-peak - meets stringent phase noise requirements for clock distribution and high-fidelity data acquisition.
Supply Flexibility	2.5 V core supply with optional 3.3 V LDO input - simplifies system-level power architecture by eliminating external regulators.
CMTI	>25 kV/μs - maintains signal integrity in noisy motor drives, inverters, and power electronics with fast-switching transients.
Operating Temp	−40°C to +125°C - qualified for under-hood automotive, industrial PLC, and aerospace avionics environments.

Pinout & Package

ADN4650BRWZ-RL7 is housed in a 20-lead wide-body SOIC package (RW-20) with 7.8 mm creepage and clearance, optimized for 5 kV_RMS reinforced isolation. Pin 1 is located at the top-left corner adjacent to the index mark.

Pin/Terminal	Circuit Role	Design Meaning
1, 20	VIN1 / VIN2	Optional 3.3 V LDO inputs for Side 1 and Side 2 - bypassed to respective GNDx with 1 µF capacitors; omitted if 2.5 V supplied directly to VDDx.
2, 4, 10 / 11, 17, 19	GND1 / GND2	Isolated ground references for input and output sides - must be kept separate to maintain galvanic barrier integrity.
3, 9 / 12, 18	VDD1 / VDD2	2.5 V core supply pins - externally tied together and bypassed with 0.1 µF capacitors to respective GNDx.
5, 6 / 7, 8	DIN1+, DIN1− / DIN2+, DIN2−	Differential LVDS inputs for Channel 1 and Channel 2 - accept ±100 mV threshold-compliant signals per TIA/EIA-644-A.
13, 14 / 15, 16	DOUT2−, DOUT2+ / DOUT1−, DOUT1+	Differential LVDS outputs - deliver 250–450 mV swing into 100 Ω loads with <100 ps pulse skew and 600 ps part-to-part skew.

Key Features

Feature	Design Value
Galvanic LVDS Isolation	Capacitive iCoupler® technology enables drop-in replacement of non-isolated LVDS buffers without layout redesign or signal conditioning.
High-Speed Timing Integrity	4.5 ns max propagation delay and 151 ps total jitter at 600 Mbps ensure sub-nanosecond synchronization across isolated domains.
Robust Power Rejection	−75 dBc PSRR suppresses switching noise from shared 2.5 V/3.3 V rails, preventing data corruption in mixed-signal systems.
Regulatory Compliance	UL 1577, VDE 0884-17, IEC/CSA 62368-1, and IEC/CSA 60601-1 certifications simplify safety approval for medical and industrial end equipment.
ESD Protection	±8 kV HBM and ±8 kV IEC 61000-4-2 across isolation barrier protect against handling and system-level transients without external clamps.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LVDS isolator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADN4651BRWZ-RL7	Same 5 kV_RMS SOIC package and 600 Mbps rating, but includes fail-safe output high for open/short/terminated inputs.	Required where idle-state logic level must be guaranteed (e.g., safety-critical control enable lines).	Select ADN4651BRWZ-RL7 when fail-safe behavior is mandatory; ADN4650BRWZ-RL7 is preferred for pure data transparency.
ISO6721FDWR	2-channel digital isolator (not LVDS-specific); 500 Mbps max, 2.5 V only, no integrated LDO, 3.75 kV_RMS in SOIC-16.	Suitable for general-purpose isolated logic, but lacks LVDS compliance, jitter performance, and drive strength for high-speed serial links.	Choose ISO6721FDWR only for cost-sensitive, lower-speed digital isolation where LVDS standards and jitter specs are not required.

Compared with ADN4651BRWZ-RL7, the ADN4650BRWZ-RL7 omits fail-safe logic - reducing latency and simplifying timing analysis for transparent data paths. Against ISO6721FDWR, it delivers higher speed, lower jitter, integrated LDO, and true LVDS compliance - making it uniquely suited for precision timing-critical isolation.

FAQ

What is the isolation voltage rating of the ADN4650BRWZ-RL7?

The ADN4650BRWZ-RL7 is rated for 5 kV_RMS isolation for 1 minute per UL 1577, with reinforced insulation certification per DIN EN IEC 60747-17 (VDE 0884-17) and IEC/CSA 62368-1. This rating applies to its 20-lead wide-body SOIC (RW-20) package, which provides 7.8 mm creepage and clearance distances.

Does the ADN4650BRWZ-RL7 support fail-safe output behavior?

No, the ADN4650BRWZ-RL7 does not implement fail-safe output logic. That feature is exclusive to the ADN4651BRWZ-RL7 and ADN4652BRWZ-RL7 variants. The ADN4650BRWZ-RL7 provides transparent LVDS signal isolation without automatic high-level assertion during input fault conditions.

Can the ADN4650BRWZ-RL7 operate from a 3.3 V supply?

Yes - the ADN4650BRWZ-RL7 accepts 3.0 V to 3.6 V on VIN1/VIN2 pins to power internal LDOs that generate regulated 2.5 V supplies for VDD1/VDD2. Alternatively, a clean 2.5 V supply can be applied directly to VDD1/VDD2, bypassing the LDOs entirely.

What is the maximum data rate supported by the ADN4650BRWZ-RL7?

The ADN4650BRWZ-RL7 supports up to 600 Mbps per channel with guaranteed timing performance, including 4.5 ns maximum propagation delay and 151 ps peak-to-peak total jitter at BER 1×10⁻¹². This enables use in JESD204B/C, high-resolution imaging, and real-time control applications.

Which safety standards does the ADN4650BRWZ-RL7 comply with?

The ADN4650BRWZ-RL7 complies with UL 1577 (5000 V_RMS), IEC/CSA 62368-1, IEC/CSA 60601-1 (1 MOPP), IEC/CSA 61010-1, CQC GB4943.1, and DIN EN IEC 60747-17 (VDE 0884-17). These certifications validate its suitability for medical, industrial, and test equipment designs.
