FSSD06 — SD/SDIO and MMC Two-Port Multiplexer March 2012 FSSD06 — SD/SDIO and MMC Two-Port Multiplexer Features Description The FSSD06 is a two-port multiplexer that allows Secure On Resistance Typically 4Ω, V =2.7V DDH Digital (SD), Secure Digital I/O (SDIO), and Multimedia f : > 120MHz toggle Card (MMC) host controllers to be expanded out to multiple cards or peripherals. This configuration enables Low On Capacitance: 9pF Typical the CMD, CLK, and D[3:0] signals to be multiplexed to Low Power Consumption: 1µA Maximum dual-card peripherals. It is optimized for 1-bit / 4-bit SD / MMC applications. Conforms to Secure Digital (SD), Secure Digital I/O (SDIO), and Multimedia Card (MMC) Specifications The architecture includes the necessary bi-directional data and command transfer capability for single high- Supports 1-Bit / 4-Bit Host Controllers (V =1.65V to DDH voltage cards or dual-voltage supply cards. The clock 3.6V) Communicating with High-Voltage (2.7-3.6V) path for the FSSD06 is a uni-directional buffer with an and Dual-Voltage Cards (1.65-1.95V, 2.7-3.6V) integrated pull-up for high-impedance mode. - V =1.65 to 3.6V, V =V to 3.6V DDH DDC1/C2 DDH Typical applications involve switching in portables and 24-Lead MLP (3.5 x 4.5mm) and UMLP Packages consumer applications: cell phones, digital cameras, home theater monitors, portable GPS units, and printers.
