NVT4857UK - memory card voltage level translator

Description

The device is an SD 3.0-compliant bidirectional dual voltage level translator with auto-direction control.

It is designed to interface between a memory card operating at 1.8 V or 3.0 V signal levels and a host with a nominal supply voltage of 1.2 V to 1.8 V.

Features

  • Supports up to 208 MHz clock rate.
  • SD 3.0 specification-compliant voltage translation to support SDR104, SDR50, DDR50, SDR25, SDR12, High-Speed and Default-Speed modes.
  • 1.2 V to 1.8 V host side interface voltage support.
  • Feedback channel for clock synchronization.
  • 100 mA 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.
