SD, SDIO, Mini SD, Micro SD and SIM Card Voltage Level Translator with EMI Filter and ESD Protection
The NVT4858 device is an SD 3.0-compliant bidirectional dual voltage level translator with auto direction control. It is designed to interface between a memory or SIM card operating between 1.65 V to 3.6 V signal levels and a host with a supply voltage of 1.08 V to 1.95 V.
The device supports SD 3.0 SDR104, SDR50, DDR50, SDR25, SDR12 and SD 2.0 High-Speed (50 MHz) and Default-Speed (25 MHz) modes. The device has an auto-enable/disable function connected to the VCCB supply pin, built-in EMI filters and robust ESD protections (IEC 61000-4-2, level 4).
This device also supports SIM card voltage level translator using CLK and two of the data lines for SD and SIM card combo sockets.

Features
Key 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
- Compliant with ISO-7816 SIM/Smart Card interface requirements
- Support SD/SIM card supply voltages with range of 1.65 V to 3.6 V
- Host microcontroller operating voltage range: 1.08 V to 1.95 V
- Feedback channel for clock synchronization
- Low power consumption by push-pull output stage with break-before-make architecture
- Automatic enable and disable through VCCB
- 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 eliminates need for external ESD diodes
- Level shifting buffers keep ESD stress away from the host (zero-clamping concept)
