Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. supplies new and original GENESYS GL9750 PCI Express 1.1 to SD 3.0 (DDR200) compliant single LUN card reader controller.

Product Description

The GL9750 is a PCI Express Rev. 1.1 compliant card reader controller that integrates a PCI Express PHY, memory card access interface, voltage regulator (3.3V to 1.2V) and card power switch.

The GL9750 supports a wide range of SD memory cards such as Secure DigitalTM (SD), SDHC, miniSD and microSD (T-Flash), MultiMediaCardTM (MMC), RS-MMC, MMCmicro and MMCmobile. It also supports high-density memory cards (up to 2TB capacity) such as SDXC, Ultra High Speed Memory Card, and SD 3.0 UHS-I.

The GL9750 supports PCI Express L1 PM sub-state, Runtime D3 (RTD3), Latency Tolerance Reporting (LTR), and Optimised Buffer Flush/Fill (OBFF) to save power.
