Description

FXL3SD206 is a voltage translator with multiplexing and de-multiplexing functions for SDIO devices. It is designed for voltage translation over a wide range of input and output levels, from 1.65V to 3.6V.

Features

■ Bi-Directional Interface between Two Levels: 1.65 to 3.6V

■ Fully Configurable: Inputs and Outputs Track VDD

■ Flexible and Programmable VDD of B and C Ports

■ Non-Preferential Power-up; either VDD Can Power Up First

■ Output Remains in 3-State until Active VDD Level is Reached

■ Output Switches to 3-state if either VDD is at GND

■ Power-off Protection

■ Bus-Hold on Data Input Eliminates the Need for SDIO Pull-up Resistors

■ 2:1 MUX/DEMUX of SDIO Devices in 24-Terminal Micro-MLP Package (2.5mm x 3.4mm)

■ Direction Control is Automatic

■ Power Switching Time (VDD_HI to VDD_LO or Reverse) is Less than 1.7µs

■ 60Mbps Throughput

■ ESD Protection Exceeds:

◾ 12KV HBM (A, B, and C port I/O to GND) (per JESD22-A114)

◾ 1KV CDM (per ESD STM5.3)

Applications

■ SDIO Devices

■ Cell Phone, PDA, Digital Camera, Portable GPS
