FSSD06 — SD/SDIO and MMC Two-Port Multiplexer
Features
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. It is optimized for
1-bit / 4-bit SD / MMC applications.
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
The architecture includes the necessary bi-directional
data and command transfer capability for single high-
voltage cards or dual-voltage supply cards. The clock
path for the FSSD06 is a uni-directional buffer with an
integrated pull-up for high-impedance mode.
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
Typical applications involve switching in portables and
consumer applications: cell phones, digital cameras,
home theater monitors, portable GPS units, and printers.
