NXS0506集成電路（IC）的轉(zhuǎn)換器電平移位器規(guī)格書PDF中文資料

1. General description

The NXS0506 is an SD 3.0-compatible bidirectional dual supply level translator with auto-direction

control. It is designed to interface between a memory card operating at 1.7 V to 3.6 V signal levels

and a host with a nominal supply voltage of 1.1 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 a built-in EMI filter and robust ESD protection (IEC 61000-4-2, level 4).

2. Features and benefits

? Supports up to 208 MHz clock rate

? SD 3.0 specification-compatible voltage translation to support: SDR104, SDR50, DDR50,

SDR25, SDR12, High-Speed and Default-Speed modes

? 1.1 V to 1.95 V host side interface voltage support

? Auto-direction sensing

? Low power consumption

? Integrated pull-up resistors: no external resistors required

? Integrated EMI filters suppress higher harmonics of digital I/Os

? Level shifting buffers keep ESD stress away from the host (zero-clamping concept)

? 16-bumps WLCSP package; pitch 0.35 mm

? ESD protection:

? HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 2 kV

? CDM ANSI/ESDA/JEDEC JS-002 Class C3 exceeds 1 kV

? IEC61000-4-2, level 4, contact discharge on all memory card-side pins exceeds 8 kV

? IEC61000-4-2, level 4, air discharge on all memory card-side pins exceeds 15 kV

? Specified from -40 °C to +85 °C

3. Applications

? Smartphone

? Mobile handsets

? Digital cameras

? Tablet PCs

? Laptop computers

? SD, MMC or microSD card readers
