Product Features and Capabilities

The modules supports   USB 2.0 signaling  with automatic detection of   low (1.5 Mbps), full (12 Mbps), and high-speed (480 Mbps) connections, ensuring seamless data transmission while maintaining ultra-low power consumption. With bidirectional isolation for both upstream and downstream ports, the module features advanced   redriving and high-speed data retiming, effectively removing input jitter and delivering an open-eye signal for superior performance.

Unmatched Protection & Compliance for Medical Applications

The module is engineered to meet the stringent demands of   ultrasound and medical imaging systems.  The Cephasonics USB Isolation Modules provide   ±8000V IEC 61000-4-2 ESD protection   across the isolation barrier, safeguarding sensitive devices from electrostatic discharge. Additionally, the module has   high common-mode transient immunity (50 kV/μs typical), ensuring stable operation even in high-noise environments.

With safety at the forefront, the module is designed to meet key   international regulatory and safety standards (pending certifications):

• UL 1577 – 5700V rms isolation for 1 minute
• CSA Component Acceptance Notice 5A  – IEC 62368-1, IEC 61010-1, and IEC 60601-1 compliance
• VDE Certificate of Conformity (pending)    – DIN V VDE V 0884-11 with   VIORM = 849 VPEAK​

​

 Optimized Power Efficiency & Extreme Durability

The Cephasonics USB Isolation Module is engineered for   ultra-low power standby operation, consuming just   1.7 mA (upstream) and 20 μA (downstream)  in USB 2.0 suspend mode.

​With a   5VDC 300mW isolated power supply, the module ensures reliable power delivery while maintaining   creepage >8mm and clearance >5mm, enhancing insulation and safety.

Designed for harsh environments, the module operates over an extended   temperature range of -55°C to +125°C, making it ideal for demanding medical and industrial applications.

Additionally, the modules have  compassed   CISPR32/EN55032 Class B emissions compliance, ensuring minimal electromagnetic interference.
