FSSD06 - SD/SDIO and MMC Two-Port Multiplexer

General Description

The FSSD06 is a two-port multiplexer that allows Secure Digital (SD), Secure Digital I/O (SDIO), and Multimedia Card (MMC) host controllers to be expanded out to multiple cards or peripherals.

This configuration enables the CMD, CLK, and D[3:0] signals to be multiplexed to dual-card peripherals.

Key Features

  • On Resistance Typically 4Ω, VDDH=2.7V.
  • ftoggle: > 120MHz.
  • Low On Capacitance: 9pF Typical.
  • Low Power Consumption: 1µA Maximum.
  • Conforms to Secure Digital (SD), Secure Digital I/O (SDIO), and Multimedia Card (MMC) Specifications.
  • Supports 1-Bit / 4-Bit Host Controllers (VDDH=1.65V to 3.6V) Communicating with High-Voltage (2.7-3.6V) and Dual-Voltage Cards (1.65-1.95V, 2.7-3.6V) - VDDH=1.65 to 3.6V, VDDC1/C2=VDDH to 3.6V.
  • 24-Lead MLP (3.5 x 4.5mm) and UMLP Packag.
