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)(纳斯达克股票代码:DIOD)今天宣布推出 PI5USB212,一款 USB 2.0 信号调节器,可在低至 2.3V 的电源电压下工作。PI5USB212 专为笔记本电脑、PC、扩展坞、电缆延长器、电视和显示器而设计,可自动检测 USB 2.0 高速连接。它还可以在驱动长达 5 米的 PCB 走线或电缆时保持信号完整性。

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.

该IC对称地增强了USB D+和D—通道以实现共模稳定性,并应用预加重来补偿符号间干扰 (ISI)。宽电源电压范围简化了系统设计,并延长了便携式和电池供电设备的工作窗口。

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.

该器件使用 I2C 命令或引脚绑定进行配置,调整信号增强和 ISI 补偿电平。它有两个控制引脚(Boost/SEN);通过不同的电阻器向下拉升压引脚可控制交流增益/预加重水平。SEN 引脚选择高、低或中等接收器灵敏度(直流增益),以确保最佳信号完整性,具体取决于信道条件。它会自动检测低速 (LS) 模式/全速 (FS) 连接,以避免在不需要时应用信号补偿。

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 和电池充电 (BC) 1.2,并支持 USB 功能,包括设备连接和高速检测,以及 5.5V 容差。它会自动检测何时没有 USB 连接器,并通过将其电源电流降低至 0.7mA(典型值),通过 RSTN 禁用引脚将其电源电流降低至 13μA(典型值)来节省能源。

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.

这个 PI5USB212 采用 12 引脚、1.6 毫米 x 1.6 毫米的四方扁平无引线 (QFN) 封装供应,批量 3,500 件,售价 2.70 美元。
