Self-Adapting USB 2.0 Signal Conditioner IC From Diodes Incorporated Saves Power and Simplifies System Design
Diodes Incorporated (Diodes) (Nasdaq: DIOD) today announces the introduction of the PI5USB212, a USB 2.0 signal conditioner that operates from a supply voltage down to 2.3V. Designed for use in notebooks, PCs, docking stations, cable extenders, TVs, and monitors, the PI5USB212 automatically detects a USB 2.0 high-speed connection. It also preserves signal integrity when driving long PCB traces or cables of up to 5 meters.
Diodes 公司（Diodes）（納斯達克股票代碼：DIOD）今天宣佈推出 PI5USB212，一款 USB 2.0 信號調節器，可在低至 2.3V 的電源電壓下工作。PI5USB212 專爲筆記本電腦、PC、擴展塢、電纜延長器、電視和顯示器而設計，可自動檢測 USB 2.0 高速連接。它還可以在驅動長達 5 米的 PCB 走線或電纜時保持信號完整性。
This IC symmetrically boosts the USB D+ and D– channels for common-mode stability and applies pre-emphasis to compensate for intersymbol interference (ISI). The wide supply voltage range simplifies system design and extends the operating window of portable and battery-powered equipment.
該IC對稱地增強了USB D+和D—通道以實現共模穩定性，並應用預加重來補償符號間干擾 (ISI)。寬電源電壓範圍簡化了系統設計，並延長了便攜式和電池供電設備的工作窗口。
The device is configured using either I2C commands or pin strapping, adjusting signal-boost and ISI-compensation levels. It has two control pins (boost/SEN); pulling the boost pin down via different resistors controls the AC gain/pre-emphasis levels. The SEN pin selects high, low, or medium receiver sensitivity (DC gain) to ensure optimum signal integrity, depending on channel conditions. It automatically detects a low-speed (LS) mode/full-speed (FS) connection to avoid applying signal compensation when not needed.
該器件使用 I2C 命令或引腳綁定進行配置，調整信號增強和 ISI 補償電平。它有兩個控制引腳（Boost/SEN）；通過不同的電阻器向下拉升壓引腳可控制交流增益/預加重水平。SEN 引腳選擇高、低或中等接收器靈敏度（直流增益），以確保最佳信號完整性，具體取決於信道條件。它會自動檢測低速 (LS) 模式/全速 (FS) 連接，以避免在不需要時應用信號補償。
The PI5USB212 is compatible with USB 2.0, OTG 2.0, and battery-charging (BC) 1.2, and supports USB features including device-attach and high-speed detection, as well as a 5.5V tolerance. It automatically detects when no USB attachment is present and saves energy by reducing its supply current to 0.7mA (typical), and 13μA (typical) when disabled via the RSTN disable pin.
PI5USB212 兼容 USB 2.0、OTG 2.0 和電池充電 (BC) 1.2，並支持 USB 功能，包括設備連接和高速檢測，以及 5.5V 容差。它會自動檢測何時沒有 USB 連接器，並通過將其電源電流降低至 0.7mA（典型值），通過 RSTN 禁用引腳將其電源電流降低至 13μA（典型值）來節省能源。
The PI5USB212 is supplied in a 12-pin, 1.6mm x 1.6mm, quad flat no-lead (QFN) package, and is available at $2.70 in 3,500-piece quantities.
這個 PI5USB212 採用 12 引腳、1.6 毫米 x 1.6 毫米的四方扁平無引線 (QFN) 封裝供應，批量 3,500 件，售價 2.70 美元。
