NVT4857UKAZ

NVT4857UKAZ is a SD 3.0-compliant bidirectional dual voltage level translator with auto-direction control. It is designed to interface between a memory card operating at 1.8V or 3.0V signal levels and a host with a nominal supply voltage of 1.2V to 1.8V. The device supports SD 3.0 SDR104, SDR50, DDR50, SDR25, SDR12 and SD 2.0 high-speed (50MHz) and default-speed (25MHz) modes. The device has an integrated voltage selectable low dropout regulator to supply the card-side I/P/O/Ps, an auto-enable/ disable function connected to the VSD supply pin, built-in EMI filters and robust ESD protections (IEC 61000-4-2, level 4). Typical applications include smart phones, mobiles handsets, digital cameras, tablet PCs, laptop computers and SD, MMC or microSD card readers.

• Supports up to 208MHz clock rate
• Feedback channel for clock synchronization
• 100mA Low dropout voltage regulator to supply the card-side I/Os
• Low power consumption by push-pull output stage with break-before-make architecture
• Automatic enable and disable through VSD
• Integrated pull-up and pull-down resistors: no external resistors required
• Integrated EMI filters suppress higher harmonics of digital I/Os
• Integrated 8 kV ESD protection according to IEC 61000-4-2, level 4 on card side
• Available in a 20 pin WLCSP package, temperature range from -40°C to +85°C
