This 14-bit SSD switch is designed for 1.35V/ 1.5V/ 1.8V supply voltage, POD_12, SSTL_135, SSTL_15 or SSTL_18 signaling and CMOS select input signals. It is designed for DDR2 or DDR3 memory bus with speed up to 5Gbps. It supports DDR3 1866 Mbps. PI2SSD3212 has a 1:2 demux or 2:1 mux topology. All 14-bit channels can be switched to one of the two ports simultaneously with the SEL input. This device also allows all ports to be disconnected. PI2SSD3212 uses Diodes' proprietary high speed switch technology providing consistent high bandwidth across all channels, with very little insertion loss, cross-talk, and bit to bit skew. It is available in a 52-pin TQFN 3.5x9x0.4mm package and 48-pin TFBGA 4.5x4.5x0.8mm package.
