PI2SSD3212A1

Description

This 14-bit signal switch is designed for eMMC HS200 and HS400 bus with speed up to 400MB/s, 1.8V or 1.2V I/Os. HS200 is the high Speed interface timing mode of up to 200MB/s at 200MHz Single Data Rate Bus and HS400 up to 400MB/s at 200MHz Dual Data Rate Bus.

In addition, it supports POD_12, SSTL_135, SSTL_15 or SSTL_18 signaling and CMOS select input signals. It can be used for DDR2, DDR3 or DDR4 memory bus switch with speed up to 5Gbps. It supports DDR3 800~2133Mbps, DDR4 1600~4266Mbps.

The PI2SSD3212A1 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.

The PI2SSD3212A1 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 48-pin TFBGA 4.5x4.5x0.8mm package.
