GL9767

PCI Express to SD Express Card Reader Controller
GL9767 is a PCI Express Rev. 2.1 compliant card reader controller which integrates PCI Express PHY, UHS-II PHY, memory card access interface, regulators (3.3V-to-1.8V and 3.3V-to-1.2V) and card power switch.
 
GL9767 supports various types of SD memory cards, such as Secure DigitalTM (SD), SDHC, miniSD and microSD (T-Flash). It supports high density memory cards (Capacity up to 128TB), such as SDXC and SDUC and ultra high speed memory cards, SD 3.0 UHS-I, SD 4.0 UHS-II and the latest generation high speed memory cards, SD 7.1 Express card and SD 8.0 Express card.
 
GL9767 supports PCI Express ASPM, L1 sub-states, Runtime D3 (RTD3 Hot/Cold), Latency Tolerance Reporting (LTR), and Optimized Buffer Flush/Fill (OBFF) for saving power consumption.
