► High common-mode transient immunity: 100 kV/μs typical
GENERAL DESCRIPTION
► Safety and regulatory approvals (28-lead SOIC_W_FP package) ► UL (pending): 5700 V rms for 1 minute per UL 1577 The ADN46241 is a quad-channel, signal isolated, low voltage ► CSA Component Acceptance Notice 5A (pending) differential signaling (LVDS) buffer that operates at up to 2.5 Gbps ► VDE certificate of conformity (pending) with very low jitter. The device integrates Analog Devices, Inc., iCoupler® technology, enhanced for high speed operation to pro- ► DIN V VDE V 0884-11 (VDE V 0884-11):2017-01 vide drop-in galvanic isolation of LVDS signal chains. AC coupling ► VIORM = 849 VPEAK (working voltage) and/or level shifting to the LVDS receivers and from the LVDS ► Enable or disable refresh (low speed output correctness check) drivers allows isolation of other high speed signals such as current ► Operating temperature range: −40°C to +125°C mode logic (CML). ► 28-lead, wide body, fine pitch SOIC-FP package with 8.3 mm The ADN4624 includes a refresh mechanism to monitor the input creepage and clearance and output states and ensure they remain the same in the absence

of data transitions (for example, at power-on). For lower power consumption and high speed operation with low ► Isolated video and imaging data jitter, the LVDS and isolator circuits rely on 1.8 V supplies. The ► Analog front-end isolation ADN4624 is fully specified over a wide industrial temperature range ► Data plane isolation and is available in a 28-lead, wide body, fine pitch SOIC-FP pack- ► Isolated high speed clock and data links age with 8.3 mm creepage and clearance (for 5.7 kV rms or 8 ► Multi-gigabit serialization/deserialization (SERDES) kVPEAK surge and impulse voltages and reinforced insulation at AC mains voltages). ► Board-to-board optical replacement (for example, short reach fiber) 1 Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329.
