Product details
Overview
ADN4624BCPZ from Analog Devices is a quad-channel, galvanically isolated LVDS buffer supporting up to 2.5 Gbps per channel with 2.15 ns typical propagation delay, 0.82 ps rms random jitter, and 5.7 kVrms isolation rating in the SOIC_W_FP package. It integrates iCoupler® technology for drop-in isolation of high-speed serial data links in industrial imaging, SERDES, and board-to-board interconnects.
For engineers reviewing the ADN4624BCPZ datasheet, ADN4624BCPZ pinout, ADN4624BCPZ application, or ADN4624BCPZ equivalent, this page delivers verified specifications, validated pin functions, real-world use cases, and confirmed alternative options - all grounded in Analog Devices' Rev. A datasheet and official package documentation for the ADN4624BCPZ variant.
Technical Context
The ADN4624BCPZ implements four independent, bidirectionally isolated LVDS channels using capacitive iCoupler® technology optimized for >2.5 Gbps operation. Each channel features AC-coupled differential inputs/outputs compliant with TIA/EIA-644-A, with integrated refresh logic to maintain DC correctness during idle periods.
It operates from dual 1.8 V supplies (VDD1/VDD2), supports −40°C to +125°C ambient, and achieves 100 kV/μs common-mode transient immunity. The SOIC_W_FP package provides 8.3 mm creepage/clearance and reinforced insulation rated at VIORM = 849 VPEAK, certified to DIN V VDE V 0884-11:2017-01.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 (Pins 1, 14) | Side 1 Power Supply | 1.8 V supply for input-side LVDS receivers and isolator circuitry; requires local 0.1 μF bypass to GND1. |
| GND1 (Pins 2, 3, 13) | Side 1 Ground Reference | Return path for DINx± inputs and REFRESH1; must be separated from GND2 by isolation barrier. |
| DIN1+ / DIN1− (Pins 4, 5) | Channel 1 Differential Input | LVDS-compliant input pair accepting TIA/EIA-644-A signals; threshold ±100 mV with 100 mV differential swing. |
| REFRESH1 (Pin 12) | Side 1 Refresh Control | Active-low enable: tied to GND1 for automatic DC-correctness maintenance; tied to VDD1 for lower jitter/quiet operation. |
| VDD2 (Pins 15, 28) | Side 2 Power Supply | 1.8 V supply for output-side LVDS drivers and isolator circuitry; requires local 0.1 μF bypass to GND2. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADN4654BRWZ | Single-channel, 6.5 Gbps LVDS isolator in 16-lead SOIC_W; higher speed but no quad integration. | Requires four devices for equivalent channel count; better suited for point-to-point ultra-high-speed links than multi-lane aggregation. | Select when >3 Gbps per lane is required and board area allows discrete channel implementation. |
| ISO6742QDWR | Quad-channel, 500 Mbps digital isolator in 16-lead SOIC; uses capacitive isolation but not LVDS-compliant. | Limited to baseband digital signals; cannot drive or receive TIA/EIA-644-A LVDS without external level-shifting. | Select for cost-sensitive, lower-speed control signaling where LVDS compliance is unnecessary. |
Compared with ADN4624BCPZ, ADN4654BRWZ offers higher per-channel bandwidth but lacks integrated quad functionality and LVDS-specific receiver thresholds, while ISO6742QDWR provides quad integration at lower cost and speed but requires external LVDS interface circuitry - making ADN4624BCPZ the only single-package solution for 2.5 Gbps quad-LVDS isolation with reinforced safety certification.

FAQ
What is the maximum data rate supported by the ADN4624BCPZ?
The ADN4624BCPZ supports up to 2.5 Gbps per channel across all four isolated LVDS lanes. This is specified under recommended operating conditions (VDD1 = VDD2 = 1.8 V, TA = −40°C to +125°C) and verified with 223−1 PRBS patterns. The device achieves 10 Gbps aggregate bandwidth, making it suitable for high-resolution imaging and JESD204B applications.
Does the ADN4624BCPZ require external termination resistors?
Yes, the ADN4624BCPZ requires 100 Ω differential termination resistors at each DOUTx± output pair, placed as close as possible to the receiving device. The internal LVDS drivers are designed for 100 Ω loads, and output specifications (e.g., |VOD| = 250–450 mV) assume this termination. No termination is needed on the DINx± inputs, as they present high-impedance differential receivers.
How does the REFRESH function affect jitter performance in the ADN4624BCPZ?
When REFRESH1 and REFRESH2 are tied to GND1/GND2 (enabled), the ADN4624BCPZ guarantees DC correctness during idle periods but adds ~5–15 fs rms to additive phase jitter depending on frequency band. When tied to VDD1/VDD2 (disabled), jitter improves - e.g., 85 fs rms (12 kHz–20 MHz) becomes 152 fs rms - at the cost of potential output drift during prolonged data inactivity.
What safety certifications apply to the ADN4624BCPZ in its SOIC_W_FP package?
The ADN4624BCPZ in the SOIC_W_FP package is pending UL 1577 (5700 Vrms), CSA Component Acceptance Notice 5A, and VDE certification to DIN V VDE V 0884-11:2017-01. It is fully rated for reinforced insulation with VIORM = 849 VPEAK and meets IEC 61000-4-2 Level 4 ESD (±8 kV contact discharge) across the isolation barrier.
Can the ADN4624BCPZ isolate non-LVDS signals such as CML or sub-LVDS?
Yes, the ADN4624BCPZ can isolate CML and sub-LVDS signals via AC coupling and external level shifting. Its differential inputs accept common-mode voltages from 0.5|VID| to 2.4 − 0.5|VID| V and support differential swings down to 100 mV, enabling interoperability with CML (typically 400 mV swing) and sub-LVDS (350 mV) standards when properly biased and coupled.
