PRODUCT BRIEF
PI2SSD3212
1.35V/ 1.5V/1.8V 14 bit 2:1 SSD Switch
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 Pericom’s 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.
