The ADN4622/ADN4624 are quad-channel, signal isolated, low-voltage differential signaling (LVDS) buffers that operate at up to 2.5 Gbps with very low jitter. The devices integrate Analog Devices, Inc., iCoupler® technology, enhanced for high-speed operation to provide drop-in galvanic isolation of LVDS signal chains. AC coupling and/or level shifting to the LVDS receivers and from the LVDS drivers allows isolation of other high-speed signals such as current-mode logic (CML).The ADN4622/ADN4624 include a refresh mechanism to monitor the input and output states and ensure they remain the same in the absence of data transitions. For lower power consumption and high-speed operation with low jitter, the LVDS and isolator circuits rely on 1.8 V supplies. The ADN4622/ADN4624 are fully specified over a wide industrial temperature range and are available in a 28-lead, wide-body, finer pitch SOIC_W_FP package with 8.3 mm creepage and clearance (for 5.7 kV rms or 8 kVPEAK surge and impulse voltages and reinforced insulation at AC mains voltages) or 6 mm × 6 mm LFCSP package with 1.27 mm creepage and clearance (for basic/functional isolation).APPLICATIONS Isolated video and imaging data Analog front-end isolation Data plane isolation Isolated high speed clock and data links Multi-gigabit SERDES Board-to-board optical replacement (for example, short reach fiber)

The ADM8323/ADM8324 are supervisory circuits that monitor power supply voltage levels and code execution integrity in microprocessor-based systems. An on-chip watchdog timer checks for activity within a preset timeout window. A reset signal can also be asserted by an external push-button switch through a manual reset input. The RESET output is either push-pull (ADM8323) or open-drain (ADM8324).A watchdog failure results in a low output on the RESET pin. A failure can be triggered either by a fast watchdog error (watchdog pulses too close together) or by a slow watchdog error (no watchdog pulse within the timeout period). This effectively gives a window to observe the watchdog pulse. The watchdog timeout is measured from the last falling edge of the watchdog input (WDI). There are eight different watchdog windows available, as shown in Table 5.Each device is available in a choice of 26 reset threshold options from 2.5 V to 5 V in 100 mV increments. There are also four reset timeout options of 1 ms, 20 ms, 140 ms, and 1120 ms (minimum). Not all device options are available as standard models. See the Ordering Guide for details.The ADM8323/ADM8324 are available in a 5-lead SOT-23 package and typically consume only 10 μA, making them suitable for use in low power portable applications.Applications Automotive Microprocessor systems Computers Controllers Intelligent instruments Portable equipment
