Control Memory Card, ET4857, ETEK Microelectronics
The ET4857 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 IC supports SD3.0 SDR104、SDR50、DDR50、SDR25、SDR12 and SD2.0 High-Speed (50MHz) and Default-Speed (25MHz) modes. The device has an integrated voltage select-able low dropout regulator to supply the card-side I/Os, an auto-enable/disable function connected to the VSD supply pin.
Features
- Feedback channel for clock synchronization
- Low power consumption by push-pull output stage with break-before-make architecture
- Automatic enable and disable through VSD
- Integrated EMI filters suppress higher harmonics of digital I/Os
