Diodes Incorporated Unveils New USB 2.0 Signal Conditioner Integrated Circuit for Consumer Electronics
Diodes Incorporated Introduces PI5USB212: A Versatile USB 2.0 Signal Conditioner for Enhanced Signal Integrity
BonChip Electronics, a leading distributor of Diodes Incorporated products, is excited to announce the availability of the PI5USB212, a groundbreaking USB 2.0 signal conditioner. This innovative IC empowers engineers to design robust and reliable USB connections in a wide range of applications.
Optimizing Signal Integrity for Long Distances
The PI5USB212 is specifically designed to address signal integrity challenges in USB 2.0 applications:
- Preserves Signal Quality: Effectively compensates for signal loss caused by long PCB traces or cables (up to 5 meters), ensuring pristine data transmission even over extended distances.
- Automatic High-Speed Detection: Automatically recognizes high-speed USB 2.0 connections, applying the necessary signal conditioning for optimal performance.
- Symmetrical Signal Boosting: Symmetrically enhances both USB D+ and D- differential signals, promoting common-mode stability and reducing noise susceptibility.
- Pre-Emphasis Compensation: Applies pre-emphasis to combat intersymbol interference (ISI), a major cause of signal degradation in high-speed data transmission.
Enhanced Flexibility and System Design Advantages
The PI5USB212 offers a high degree of flexibility and simplifies system design:
- Wide Supply Voltage Range: Operates from a supply voltage as low as 2.3 V, ideal for portable and battery-powered devices. This broad voltage range simplifies power supply design and extends operational flexibility.
- Configurable Signal Boost and ISI Compensation: Allows engineers to fine-tune signal conditioning based on specific application requirements. Configuration can be achieved through either I2C commands or pin strapping for optimal control.
- Automatic Low-Speed Mode Detection: Intelligently detects low-speed (LS) or full-speed (FS) USB connections, automatically disabling signal conditioning when not necessary, minimizing power consumption.
- USB Compatibility and Feature Support: Fully compatible with USB 2.0, OTG 2.0, and battery-charging (BC) 1.2 specifications. Additionally, it supports essential USB features like device-attach and high-speed detection, with a robust 5.5 V tolerance for voltage variations.
Low-Power Operation and Easy Integration
The PI5USB212 is designed for low-power applications:
- Automatic Power Saving: When no USB connection is detected, the PI5USB212 automatically reduces its power consumption to a mere 0.7 mA (typical). For complete power shutoff, a dedicated RSTN disable pin allows for further power savings, drawing only 13 µA (typical).
- Easy Integration: The compact package and configurable options make the PI5USB212 simple to integrate into various USB 2.0 designs.
Applications for the PI5USB212
The PI5USB212 is suitable for a wide range of applications where reliable USB 2.0 data transmission is critical:
- Laptops and PCs
- Docking Stations
- Cable Extenders
- Televisions
- Monitors
- And many other USB 2.0 peripheral devices
