GL3520 电子元器件 GENESYS/创惟科技 封装QFN-88 USB 3.0集线器控制器

DESCRIPTION
Genesys GL3520-22 is a 4-port, low-power, and configurable hub controller. It is compliant with the USB3.0 specification. GL3520-22 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. GL3520-22 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, GL3520-22 has built-in 5V to 3.3V regulator, which saves customers’ BOM cost, and eases for PCB design.
GL3520-22 features the native fast-charging and complies with USB-IF battery charging specification rev1.2, it could fast-charge Apple, Samsung Galaxy devices, and any device complaint with BC1.2/1.1. It also allows portable devices to draw up to 1.5A from GL3520-22 charging downstream ports (CDP1) or dedicated charging port (DCP2). It can enable systems to fast charge handheld devices even during “Sleep” and “Power-off” modes.

FEATURES
Compliant with USB Specification Revision 3.0
- Upstream port supports super speed(SS) high speed(HS) and full speed(FS) traffic
- Downstream ports support SS, HS, FS, and low speed(LS) traffic
- 1 control pipe and 1 interrupt pipe
- Backward compatible to USB specification Revision 2.0/1.1
Featuring fast-charging on all downstream ports and upstream port
- Compliant with USB Battery Charging Revision v1.2, supporting CDP, DCP, and ACA-Dock
- Downstream ports can be turned from a Standard Downstream Port (SDP) into Charging Downstream Port (CDP) or Dedicated Charging Port (DCP)
- Downstream devices can be charged while upstream VBUS is not present, which can be applied on wall charger applications
- Upstream port is capable of charging and data communicating simultaneously for portable devices supporting ACA-Dock or proprietary charging protocols, such as Sony Z1 and ZL
