SL2.1A USB2.0 HIGH SPEED 4-PORT HUB CONTROLLER SMD SOP16

Overview

SL2.1A is a high-integration, high-performance, low-power USB2.0 hub master chip; this chip Using STT technology, single power supply mode, the chip power supply voltage is 5v, the internal integrated 5V to 3.3V, only need

Add a filter capacitor to the external power supply; the chip comes with a reset circuit, and the low-power technology makes it more outstanding.

The chip can use an external crystal, or it can use a built-in crystal. If using the built-in crystal, it is required

Ground the chip's XI input.

• Perfect support for USB2.0 high speed (480MHz), USB2.0 full speed (12MHz), and low speed mode (1.5MHz)
• Integrated 12M crystal oscillator
• Integrated 12MHz-to-480MHz PPL(Phase Lock Loop)
• Adopting Single Transaction Translator (STT) technology, it is the most cost-effective solution in the *TT series
• Supports automatic enumeration switching from self-powered to bus-powered
