Product Details
The ADN4620/ADN4621 are dual-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 ADN4620/ADN4621 include a refresh mechanism to monitor the input and output states and ensure that 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 jitter, the isolator circuits rely on 1.8 V supplies, while 3.3 V supplies are used for LVDS receivers to support the full common-mode range with an input voltage range (input common mode plus differential input voltage) of 0 V to 2.4 V per Table 2 in the data sheet.
The devices are fully specified over a wide industrial temperature range and are available in a compact SSOP package with 5.3 mm creepage (for reinforced insulation at ac mains voltages) or a wide SOIC_IC package with 15.1 mm creepage (for high working insulation voltages up to 1500 V peak, reinforced).
APPLICATIONS
