General Description

The FXL2SD106 is a configurable dual-voltage-supply translator designed for both uni-directional and bidirectional voltage translation between two logic levels. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the VCCA level, and the B port tracks the VCCB level. This allows for bi-directional voltage translation over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V and 3.3V.

The FXL2SD106 is specifically designed as a translator to interface with the SDIO standard. I/O capacitance is managed to meet the SD maximum capacitance specification. The B side ESD performance allows interface as an external card and the part can handle 80 Mbps throughput when translating between 1.8V and 2.5V.

The device remains in 3-state until both VCCs reach active levels allowing either VCC to be powered-up first. Internal power down control circuits place the device in 3-state if either VCC is removed.

The OE input, when low, disables both the A and B ports by placing them in a 3-state condition. The FXL2SD106 is designed so that both control pins (OE and CLK IN) are supplied by VCCA.

The device senses an input signal on A or B port automatically. The input signal is transferred to the other port.

Features

  • Bi-directional interface between two levels from 1.1V to 3.6V
  • Fully configurable: Inputs and outputs track VCC level
  • Non-preferential power-up; either VCC may be powered-up first
  • Outputs remain in 3-state until active VCC level is reached
  • Outputs switch to 3-state if either VCC is at GND.
  • Power-off protection
  • Bushold on data inputs eliminates the need for SDIO pull-up resistors
  • Control input (OE and CLK IN) are referenced to VCCA voltage
  • Packaged in 16-terminal DQFN (2.5mm x 3.5mm)
  • Direction control not needed
  • 80 Mbps throughput when translating between 1.8V and 2.5V
  • ESD protection exceeds:
    • 12kV HBM (B port I/O to GND) - (per JESD22-A114 & Mil Std 883e 3015.7)
    • 8kV HBM (A port I/O to GND) - (per JESD22-A114 & Mil Std 883e 3015.7)
    • 1kV CDM - (per ESD STM 5.3)
