GL3520-21-规格书

GENERAL DESCRIPTION

Genesys GL3520-21 is a 4-port, low-power, and configurable hub controller. It is compliant with the USB3.0

specification. GL3520-21 integrates Genesys Logic self-developed USB 3.0 Super Speed transmitter/receiver

physical layer (PHY) and USB 2.0 High-Speed PHY. It supports Super Speed, Hi-Speed, and Full-Speed USB

connections and is fully backward compatible to all USB 2.0 and USB 1.1 hosts. GL3520-21 also implements

multiple TT* (Note1) architecture providing dedicated TT* to each downstream (DS) port, which guarantees

Full-Speed(FS) data passing bandwidth when multiple FS devices perform heavy loading operations.

Furthermore, GL3520-21 has built-in 5V to 3.3V regulator, which saves customers’ BOM cost, and eases for

PCB design.
