ISOUSB211中文资料低发射、高速/全速/低速隔离式 USB 中继器数据手册TI规格书

描述 Description

ISOUSB211 is a galvanically-isolated USB 2.0 compliant repeater supporting low speed (1.5 Mbps) , full speed (12 Mbps) and high speed (480 Mbps) signaling rates. The device supports automatic connect and speed detection, reflection of pull-ups/pull-downs, and link power management allowing drop-in USB hub, host, peripheral and cable isolation. The device also supports automatic role reversal - if after disconnect, a new connect is detected on the Upstream facing port, then the Upstream and Downstream port definitions are reversed. The ISOUSB211 has inbuilt programmable equalization to cancel signal loss caused by board traces, which helps in meeting USB2.0 high-speed TX and RX eye-diagram templates. This device uses a silicon dioxide (SiO2) insulation barrier with a withstand voltage of up to 5700 VRMS and a working voltage of 1500 VRMS. Used in conjunction with isolated power supplies, the device protects against high voltage, and prevents noise currents from the bus from entering the local ground. The ISOUSB211 device is available for both basic and reinforced isolation (seeReinforced and Basic Isolation Options ). It supports a wide ambient temperature range of –40°C to +120°C. The device is available in the small foot-print SSOP-28 (28-DP) package.
