The TS3DDR3812RUAR from Texas Instruments is a specialized 12-channel, 1:2 multiplexer/demultiplexer switch engineered for DDR3 applications. This device supports the DDR3 SDRAM Standard (JESD79-3D) and provides a significant bandwidth of 1.675 GHz, making it suitable for high-speed memory interfaces.
Key electrical characteristics include a low propagation delay of 40 ps (typical), low bit-to-bit skew of 6 ps (typical), and a low, flat ON-state resistance of 8 Ω (typical). The device also features low input/output capacitance (5.6 pF typical) and low crosstalk (-43 dB typical at 250 MHz). It operates within a VCC range of 3V to 3.6V, with rail-to-rail switching on data I/O ports.
The TS3DDR3812RUAR is housed in a 42-pin WQFN package and is designed for surface mount applications. It operates across a temperature range of -40°C to 85°C. The switch offers independent control for upper and lower 6-channel banks via SEL1 and SEL2 inputs, with an option to control all 12 channels with a single GPIO by connecting SEL1 and SEL2 externally. An EN input facilitates a high-impedance (Hi-Z) state for power saving.
This component is an excellent choice for memory systems requiring efficient signal routing and switching for DDR3 memory modules.
