6-Bit Bi-directional Level Shifter for SD 3.0-SDR104 Compliant Memory Card Application Features Description ÎÎSupports up to 208 MHz clock rate The device is an SD 3.0-compliant bidirectional dual voltage level
translator without direction pin control. It can translate the memory card voltage to 1.8V or 3.0V signal levels from 1.2V to 1.8V of
host side and supports SD 3.0 SDR104(208Mhz), SDR50(100Mhz),
DDR50(50Mhz), SDR25(50Mhz), SDR12(25Mhz) and SD 2.0
High-Speed (50 MHz) and Default-Speed (25 MHz) modes. ÎÎSupports 1.2V to 1.8V host side interface voltage
ÎÎVoltage translation supports SDR104, SDR50, DDR50, SDR25, SDR12, High-Speed and Default-Speed modes and comply SD
3.0 specification ÎÎAutomatic enable and disable through VSD supply pin To supply the memory card I/Os, the device has an integrated
voltage selectable regulator and an auto-enable/disable function
that connects to the VSD supply pin. The device also has built-in
EMI filters and ESD protections. ÎÎBuilt-in 100mA Low dropout voltage regulator to supply the
voltage of memory card I/Os ÎÎIntegrated pull-up and pull-down resistors
ÎÎIntegrated EMI filters for digital I/Os
ÎÎOn card side, supports 8 kV ESD protection(IEC 61000-4-2,
level 4) Applications ÎÎLevel shifting buffers keep ESD stress away from the host ÎÎSmart phones ÎÎTotally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) ÎÎMobile handsets ÎÎHalogen-and Antimony-Free. “Green” Device (Note 3) ÎÎDigital cameras ÎÎFor automotive applications requiring specific change control ÎÎTablet PCs (i.e. parts qualified to AEC-Q100/101/200, PPAP capable,
and manufactured in IATF 16949 certified facilities), please
