High Voltage Protection for the NVIDIA Jetson AI Module
Bringing Server-Class Performance to the Edge
Advancements in artificial intelligence (AI) have propelled the areas of robotics, healthcare, genomic sequencing, agriculture, manufacturing, and beyond. NVIDIA®’s Jetson AI solutions offer powerful computational capabilities to enable these applications, but with great power comes great need for high voltage protection. Analog Devices, Inc. (ADI)’s giga-speed isolated data solutions and isolated power converters provide high voltage data and protocol isolation for reliable operation in the face of electrical noise and voltage surges, effectively meeting NVIDIA Jetson system needs without compromising performance.
NVIDIA Jetson Meets High Voltage Protection
Below are two examples integrating NVIDIA Jetson processing and ADI’s high voltage protection isolation solutions.
ADN4624 LVDS 2.5 Gbps
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 ADI’s iCoupler® technology, which is 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).
ADuM4165 High Speed USB 2.0
The ADuM4165/ADuM41661 are USB 2.0 port isolators using ADI’s iCoupler technology to dynamically support all USB 2.0 data rates: low (1.5 Mbps), full (12 Mbps), or high (480 Mbps), as required. The devices support host isolation with automatic speed negotiation as well as peripheral isolation.
ADuM6028 isoPower DC-to-DC Converter
The ADuM6020/ADuM6028 are isoPower®, integrated, isolated DC-to-DC converters. Based on the ADI iCoupler technology, these converters provide regulated, isolated power that is below CISPR22 Class B limits at full load on a 2 layer printed circuit board (PCB) with ferrites. Common voltage combinations and the associated current output levels are shown in Table 1 through Table 4 in the data sheet.
ADuM341E Digital Isolator
The ADuM340E/ADuM341E/ADuM342E are quad-channel digital isolators based on ADI iCoupler technology. Combining high speed, complementary metal-oxide semiconductor (CMOS), and back-to-back monolithic air core transformer technology, these isolation components provide outstanding performance characteristics and meet CISPR 32/EN 55032 Class B limits at 5 Mbps. The maximum propagation delay is 10 ns with a pulse width distortion of less than 3 ns at 5 V operation. Channel matching is tight at 3.0 ns maximum.
