Description
- The TUSB2046BIVFR is a 4-port CMOS full-speed Universal Serial Bus Hub provides one upstream port and four downstream ports in compliance with the Universal Serial Bus (USB) specification as a full-speed hub. Because this device is implemented with a digital state machine instead of a microcontroller, no firmware programming is required. Fully compliant USB transceivers are integrated into the ASIC for all upstream and downstream ports. The downstream ports support full-speed and low-speed devices by automatically setting the slew rate according to the speed of the device attached to the ports. The configuration of the BUSPWR pin selects either the bus-powered or the self-powered mode. Configuring the GANGED input determines the power switching and over-current detection modes for the downstream ports.
- Fully compliant with USB specification as a full-speed hub
- 3.3V Low-power ASIC logic
- Integrated USB transceivers
- State machine implementation requires no firmware programming
- One upstream port and four downstream ports
- All downstream ports support full-speed and low-speed operations
- Self-powered and bus-powered mode
- Power switching and overcurrent reporting is provided ganged or per port
- Supports suspend and resume operations
- Supports programmable vendor ID and product ID with external serial EEPROM
- 3-state EEPROM interface allows EEPROM sharing
- Push-pull outputs for PWRON eliminate need for external pull-up resistors
- Noise filtering on OVRCUR provides immunity to voltage spikes
- Low EMI emission achieved by a 6MHz crystal input
- Enhanced system ESD performance
- No special driver requirements, works seamlessly with any operating system with USB stack support
- Supports 6MHz operation through a crystal input or a 48MHz input clock
- Green product and no Sb/Br
- Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
