ADN4624BCPZ-RL7 - Quad LVDS Isolator 2.5Gbps | Analog Devices
MPN: ADN4624BCPZ-RL7 ✓ Hoạt độngADN4624BCPZ-RL7 Tóm tắt
A digital isolator is a component that provides galvanic isolation between two circuits while allowing digital signals to pass across the isolation barrier. In the hierarchy of isolation components, a digital isolator is a type of signal isolator, which falls under the broader category of isolation components used in power management and signal conditioning. The ADN4624 specifically isolates LVDS signals, which are differential, low-voltage, high-speed signals commonly used in high-speed data transmission.
Key features include four isolated LVDS channels (4+0 configuration), support for 1.7 V to 1.9 V supply voltages on both sides (VDD1 and VDD2), and an operating temperature range of -40°C to +125°C. The device ensures very low jitter, making it suitable for high-speed serial links where signal integrity is critical. The 5.7 kV rms isolation rating provides robust protection against voltage transients and ground potential differences.
Technically, the ADN4624 uses iCoupler technology, which employs chip-scale transformers to transmit data across the isolation barrier, offering advantages over optocouplers in terms of speed, power consumption, and reliability. The device supports AC coupling and/or level shifting to LVDS receivers and from LVDS drivers, simplifying interface design. The 32-lead WFQFN package with exposed pad aids in thermal management and is suitable for space-constrained applications.
Typical applications include isolated high-speed data acquisition systems, industrial fieldbus interfaces, medical equipment requiring patient isolation, and communication backplanes. The device is ideal for systems where high-speed data must cross an isolation barrier without compromising signal integrity.
When designing with the ADN4624, ensure proper PCB layout with adequate spacing for isolation, and place decoupling capacitors close to the VDD1 and VDD2 pins. The exposed pad should be connected to the appropriate ground plane for thermal performance.

Ghi chú thiết kế
For optimal isolation performance, maintain a minimum creepage distance of 8 mm between the input and output sides on the PCB. Use a ground plane on each side of the isolation barrier, and avoid routing traces across the barrier. Place decoupling capacitors (0.1 µF and 10 µF) close to each VDD pin, connecting to the respective ground. The exposed pad should be soldered to a thermal pad connected to GND1 or GND2 for heat dissipation.
Route LVDS traces as differential pairs with controlled impedance (typically 100 ohms). Keep trace lengths matched and minimize vias to reduce signal skew. Place the isolator close to the LVDS connector or transceiver to minimize trace length. Avoid crossing the isolation barrier with any copper traces, as this can compromise isolation. Use a solid ground plane on each side, and consider adding stitching vias around the isolation barrier to reduce EMI.
The ADN4624BCPZ-RL7 operates from 1.7 V to 1.9 V supplies. Ensure that both VDD1 and VDD2 are within this range and are adequately decoupled. Use low-ESR ceramic capacitors (0.1 µF and 10 µF) placed as close as possible to the VDD pins. If the supply voltage is noisy, consider adding a ferrite bead in series. The device's power consumption is [DATA_NEEDED: power consumption], so ensure the supply can handle the load.
