Product details
Overview
ADN4622BCPZ from Analog Devices is a quad-channel LVDS digital isolator with 2 forward + 2 reverse channel configuration, 5.7 kVrms reinforced isolation rating, 2.5 Gbps per channel data rate, 2.15 ns typical propagation delay, and ±8 kV IEC 61000-4-2 ESD protection - deployed in isolated high-speed video links and multi-gigabit SERDES interfaces.
For engineers reviewing the ADN4622BCPZ datasheet, ADN4622BCPZ pinout, ADN4622BCPZ application, or ADN4622BCPZ equivalent, key selection criteria include its 2.5 Gbps LVDS isolation capability, 5.7 kVrms SOIC_W_FP package insulation, refresh-enabled low-speed output correctness check, and compatibility with TIA/EIA-644-A signal levels in harsh industrial environments.
Technical Context
The ADN4622BCPZ integrates iCoupler® technology to provide galvanic isolation between two independently powered domains while preserving LVDS signal integrity. Its dual-supply architecture uses 1.8 V for core logic and isolator circuits and 3.3 V for I/O buffers, enabling interoperability with standard LVDS transceivers.
It implements a configurable refresh mechanism that monitors input/output state alignment during idle periods, ensuring deterministic output behavior without data transitions. The device supports full-duplex operation across two bidirectional channels (2+2), with channel-to-channel skew as low as 38 ps in the SOIC_W_FP package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 2.5 Gbps per channel - supports multi-gigabit serial links without retiming or protocol translation |
| Isolation Rating | 5.7 kVrms - enables reinforced insulation for AC mains-connected equipment per UL 1577 and VDE 0884-17 |
| Propagation Delay | 2.15 ns typical - preserves timing budgets in high-speed backplane and imaging data paths |
| Jitter (RMS) | 0.82 ps rms random jitter - maintains signal integrity for 10−12 BER in 2.5 Gbps PRBS applications |
| Common-Mode Transient Immunity | 100 kV/μs typical - sustains reliable operation in noisy motor drive or power converter environments |
| Supply Voltages | 1.8 V (VDD1/VDD2) + 3.3 V (VIO1/VIO2) - separates low-noise core logic from robust I/O interface |
| ESD Protection | ±8 kV contact discharge (IEC 61000-4-2) - eliminates need for external TVS on isolated LVDS lines |
Pinout & Package
ADN4622BCPZ is housed in a 28-lead wide-body finer-pitch SOIC_W_FP package (RN-28-1) with 8.3 mm creepage and clearance, optimized for reinforced insulation at AC mains voltages. Pinout follows standard LVDS isolator layout with side-separated power, ground, and differential I/O groups.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, VDD2 | Core supply inputs | 1.8 V supplies for isolator core and LVDS receiver/driver logic on respective sides |
| VIO1, VIO2 | I/O buffer supplies | 3.3 V supplies for LVDS input threshold and output swing compliance |
| GND1, GND2 | Reference grounds | Independent ground domains per side - no shared reference across isolation barrier |
| DIN1+/− to DIN4+/− | Differential LVDS inputs | Accept TIA/EIA-644-A compliant signals; support AC-coupled or DC-coupled interface |
| DOUT1+/− to DOUT4+/− | Differential LVDS outputs | Drive 100 Ω terminated loads with 250–450 mV differential swing and <150 mV peak-to-peak offset |
| REFRESH1, REFRESH2 | Refresh control inputs | Enable/disable low-speed output correctness monitoring; tie to GNDx for active refresh |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADN4624BCPZ | 4 forward-only channels; same 5.7 kVrms, 2.5 Gbps, SOIC_W_FP package | Used where unidirectional high-speed data flow dominates (e.g., sensor-to-processor only) | Select when full-duplex channel pairing is unnecessary and higher aggregate throughput is prioritized |
| ISO6742QDWR | 2-channel, 50 Mbps max, 5 kVrms, SOIC-16; CMOS-based, not LVDS | Suitable for control signaling or low-speed status monitoring, not high-speed data | Choose only for cost-sensitive, low-bandwidth isolation where LVDS compatibility is not required |
Compared with ADN4622BCPZ, ADN4624BCPZ offers higher unidirectional throughput but lacks reverse channels, while ISO6742QDWR provides basic isolation at <2% of the speed - making ADN4622BCPZ the sole option for 2.5 Gbps bidirectional LVDS isolation with reinforced safety certification.

FAQ
What is the maximum data rate supported by the ADN4622BCPZ?
The ADN4622BCPZ supports up to 2.5 Gbps per channel across all four LVDS channels. This is validated under standard operating conditions (VDD = 1.8 V, VIO = 3.3 V, TA = 25°C) using a 223−1 pseudorandom bit stream. The device maintains this rate with total jitter ≤70 ps at 10−12 BER, making it suitable for high-fidelity serial video and SERDES applications where timing margin is constrained.
Does the ADN4622BCPZ require external level-shifting circuitry for LVDS interfacing?
No, the ADN4622BCPZ does not require external level-shifting circuitry. Its integrated LVDS receivers and drivers comply fully with TIA/EIA-644-A specifications, accepting differential input voltages from ±100 mV and delivering 250–450 mV differential output swing into 100 Ω loads. The separate VIO1/VIO2 supplies (3.0–3.6 V) ensure proper I/O voltage referencing without external components.
How does the refresh function operate in the ADN4622BCPZ?
The refresh function in the ADN4622BCPZ monitors input and output states during data inactivity to ensure output correctness. When REFRESH1 or REFRESH2 is tied to GNDx, the internal circuitry periodically checks for state alignment between DINx and DOUTx. If mismatch is detected due to leakage or transient upset, the output is corrected - guaranteeing deterministic behavior without requiring host-side polling or error correction protocols.
What safety certifications apply to the ADN4622BCPZ in its SOIC_W_FP package?
The ADN4622BCPZ in the 28-lead SOIC_W_FP package (RN-28-1) is certified to UL 1577 (5700 Vrms/1 min), VDE 0884-17 (reinforced, 849 Vpeak), IEC/EN/CSA 62368-1, IEC/CSA 61010-1, IEC/CSA 60601-1 (2 MOPP), and CQC GB4943.1. These approvals validate its use in medical, industrial, and test equipment requiring reinforced insulation at AC mains potentials.
Can the ADN4622BCPZ be used with 1.2 V or 2.5 V I/O supplies instead of 3.3 V?
No - the ADN4622BCPZ specifies VIO1 and VIO2 supply range as 3.0 V to 3.6 V only. Operation outside this range is not characterized or guaranteed. Using 1.2 V or 2.5 V violates the recommended operating conditions and risks failure to meet LVDS threshold compliance (±100 mV), differential output swing (250–450 mV), or common-mode voltage range (0.5|VID| to 2.4 − 0.5|VID| V), potentially causing link instability or interoperability failure with standard LVDS transceivers.
