Diodes Incorporated (Nasdaq: DIOD) debuts the PI5USB212, a cutting-edge USB 2.0 signal conditioner IC poised to redefine power efficiency and system design standards across electronic devices. The PI5USB212 sets a new benchmark for performance, catering to a diverse range of applications including notebooks, PCs, docking stations, cable extenders, TVs, and monitors.
Engineered to operate seamlessly with a supply voltage as low as 2.3V, the PI5USB212 automatically detects USB 2.0 high-speed connections, ensuring uninterrupted functionality. Its standout feature lies in its ability to maintain signal integrity over extended distances of up to 5 meters, making it an ideal solution for various scenarios.
Key to its performance is its ability to ensure common-mode stability by symmetrically boosting the USB D+ and D– channels. Additionally, it employs pre-emphasis to mitigate intersymbol interference (ISI), enhancing signal quality further. The broad supply voltage range not only simplifies system design but also extends the operational capability of portable and battery-powered devices.
Flexibility is a cornerstone of the PI5USB212’s design, offering users the option to adjust signal boost and ISI-compensation levels through either I2C commands or pin strapping. With two control pins (boost/SEN), users can fine-tune AC gain/pre-emphasis levels and select receiver sensitivity (DC gain) to optimize signal integrity based on channel conditions.
Fully compliant with USB 2.0, OTG 2.0, and battery-charging (BC) 1.2 standards, the PI5USB212 supports essential USB features like device-attach and high-speed detection. It boasts a 5.5V tolerance and automatically detects low-speed (LS) mode/full-speed (FS) connections, conserving energy by reducing supply current when no USB attachment is detected.
Packaged in a compact 12-pin, 1.6mm x 1.6mm, quad flat no-lead (QFN) package, the PI5USB212 is available at a competitive price of $2.70 in quantities of 3,500 pieces.
