Product details
Overview
ADN4620BRIZ from Analog Devices is a dual-channel, 2.5 Gbps LVDS signal isolator with 7.5 kVRMS reinforced isolation, integrated iCoupler® technology, and 2.15 ns typical propagation delay. It features two forward channels, 1.8 V core supply with 3.3 V I/O, and operates from −40°C to +125°C - designed for high-speed data plane isolation in industrial SERDES and analog front-end systems.
For engineers reviewing the ADN4620BRIZ datasheet, ADN4620BRIZ pinout, ADN4620BRIZ application, or ADN4620BRIZ equivalent, this page delivers verified specifications, safety-certified package details (20-lead SSOP, 5.3 mm creepage), real-world timing performance (40 ps total jitter at 1×10⁻¹² BER), and validated alternative options for multigigabit isolated link design.
Technical Context
The ADN4620BRIZ implements galvanically isolated LVDS buffering using high-speed capacitive iCoupler® technology, enabling drop-in replacement of optocouplers in 2.5 Gbps serial links without AC coupling redesign. Its dual-forward architecture supports unidirectional high-speed data transmission across isolation barriers while maintaining TIA/EIA-644-A compliance.
It employs separate 1.8 V core supplies (VDD1/VDD2) for low-jitter internal logic and 3.3 V I/O supplies (VIO1/VIO2) to sustain full LVDS common-mode range (0 V to 2.4 V). A refresh mechanism ensures output state retention during DC/idle conditions, critical for power-on stability in SERDES initialization sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 7.5 kVRMS (1 min), VIORM = 1500 VPEAK - certified for reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17) |
| Max Data Rate | 2.5 Gbps per channel - supports PCIe Gen2-equivalent serial links without retiming |
| Propagation Delay | 2.15 ns typical - enables sub-nanosecond timing alignment in synchronous backplane interfaces |
| Total Jitter (BER 1e−12) | 40 ps peak-to-peak - meets jitter budget requirements for 2.5 Gbps NRZ signaling |
| Common-Mode Transient Immunity | 70 kV/μs typical - maintains signal integrity in noisy motor drive or power converter environments |
| ESD Protection | ±8 kV IEC 61000-4-2 contact discharge - eliminates need for external TVS on isolated LVDS lines |
| Supply Configuration | 1.8 V core / 3.3 V I/O - decouples low-noise logic operation from robust LVDS driver voltage headroom |
Pinout & Package
ADN4620BRIZ is housed in a 20-lead Shrink Small Outline Package (SSOP) with 5.3 mm creepage and clearance, rated for 3750 VRMS isolation. The package supports reinforced insulation per IEC 62368-1 and IEC 60601-1 (2 MOPP).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–8 (DIN1+, DIN1−, DIN2+, DIN2−, REFRESH1, VDD1, VIO1, GND1) | Primary-side input interface | LVDS inputs, refresh control, and dual-supply rails for side 1 - REFRESH1 enables/disable refresh on input side |
| 9–20 (DOUT1+, DOUT1−, DOUT2+, DOUT2−, REFRESH2, VDD2, VIO2, GND2) | Secondary-side output interface | Isolated LVDS outputs, refresh control, and dual-supply rails for side 2 - independent REFRESH2 allows asymmetric refresh enable |
| VDD1/VDD2 | Core logic supply | 1.8 V ±0.1 V supply for internal iCoupler® and logic - low-voltage operation minimizes switching jitter |
| VIO1/VIO2 | LVDS I/O supply | 3.3 V supply for differential drivers/receivers - ensures full 0 V to 2.4 V common-mode range compliance |
Key Features
| Feature | Design Value |
|---|---|
| Dual forward-channel topology | Enables point-to-point high-speed data forwarding (e.g., ADC digital output to FPGA) without reverse-path latency overhead |
| Refresh mechanism with REFRESH pins | Prevents output latch-up during idle periods - configurable per side to reduce power when one channel is inactive |
| 70 kV/μs CMTI | Guarantees deterministic output behavior in high-dV/dt environments like SiC inverter gate drives or CT sensor interfaces |
| 1.8 V core + 3.3 V I/O partitioning | Decouples jitter-sensitive logic from I/O voltage swing requirements - improves phase noise margin in clock distribution |
| UL 1577 & VDE 0884-17 certification | Validates safety compliance for medical (60601-1), industrial (61010-1), and consumer (62368-1) end equipment without additional system-level testing |
Applications
| Analog Front-End Isolation | Data Plane Isolation |
|---|---|

Use Value: Enables modular board design with independent power sequencing and fault containment without signal integrity degradation. |
| Isolated High-Speed Clock & Data Links | Multigigabit SERDES |
Use Scenario: Distributing low-jitter clock and parallel data from a master timing controller to isolated slave ADC/DAC modules in test equipment. IC Role / Device Role / Timing Role: Simultaneous isolation of clock and data LVDS pairs with matched propagation delay (<19 ps duty cycle skew) and <0.82 ps rms random jitter.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADN4621BRIZ | 1 forward + 1 reverse channel configuration; identical isolation rating, jitter, and supply specs | Supports bidirectional control signaling (e.g., I²C over isolation) alongside main data path | Select when reverse-channel communication (e.g., status feedback, configuration) is required across the barrier |
| ISO7821FDWWR | 2-channel, 100 Mbps max rate; 5 kVRMS isolation; 3.3 V only supply; higher propagation delay (12 ns) | Limited to lower-speed industrial bus isolation (RS-485, CAN FD physical layer), not suitable for 2.5 Gbps links | Choose only for cost-sensitive, non-high-speed applications where 2.5 Gbps capability is unnecessary |
Compared with ADN4620BRIZ, ADN4621BRIZ provides bidirectional flexibility at identical speed and isolation, while ISO7821FDWWR offers lower-cost isolation for legacy industrial buses but cannot support multigigabit data rates - making ADN4620BRIZ the sole option for 2.5 Gbps LVDS isolation with reinforced safety certification.

FAQ
What is the isolation voltage rating of the ADN4620BRIZ?
The ADN4620BRIZ has a 7.5 kVRMS isolation rating (1 minute test) in its 20-lead SSOP package, with VIORM = 1500 VPEAK and VIOWM = 1061 VRMS. It is certified to UL 1577, IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and pending DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation - fully documented in the ADN4620BRIZ datasheet Section 6.
Does the ADN4620BRIZ support bidirectional communication?
No, the ADN4620BRIZ is configured for two forward channels only (2+0). For bidirectional capability, the pin-compatible ADN4621BRIZ (1+1 configuration) must be used. Both share identical isolation, jitter, and supply specifications, but ADN4620BRIZ does not provide reverse-path signal transfer.
What supply voltages does the ADN4620BRIZ require?
The ADN4620BRIZ requires dual supplies per side: 1.8 V (±0.1 V) for VDD1/VDD2 (core logic) and 3.3 V (3.0 V to 3.6 V) for VIO1/VIO2 (LVDS I/O). This separation optimizes jitter performance while ensuring full TIA/EIA-644-A compliance across the 0 V to 2.4 V common-mode input range.
What is the maximum data rate supported by the ADN4620BRIZ?
The ADN4620BRIZ supports up to 2.5 Gbps per channel with guaranteed timing performance, including 40 ps total jitter at 1×10⁻¹² BER and 2.15 ns typical propagation delay. This enables direct replacement of fiber or high-speed optocouplers in JESD204B/C, CPRI, and proprietary SERDES links.
Is the ADN4620BRIZ RoHS compliant and lead-free?
Yes, the ADN4620BRIZ is RoHS compliant and lead-free, manufactured in accordance with Analog Devices' environmental policy and EU Directive 2011/65/EU. Full compliance documentation, including material declarations and test reports, is available via Analog Devices' product page for ADN4620BRIZ.
