PI2DDR3212  
1.35V/ 1.5V/1.8V 14 bit 2:1 DDR3/DDR4 Switch  
Features  
Description  
Î14 bit 2:1 switch that supports DDR3 800 2133Mbps, DDR4  
is 14-bit DDR3/DDR4 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  
DDR3 or DDR4 memory bus with speed up to 5Gbps. It  
supports DDR3 800 2133Mbps and DDR4 1600~4266 Mbps.  
1600~4266 Mbps  
ÎVDD 1.35V/ 1.5V/ 1.8V  
ÎFlow through pinout option for easy layout  
ÎSEL and Global Enable  
PI2DDR3212 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. is device also allows all ports to be  
disconnected.  
Î110 µA typ. operating current at 1.35V VDD.  
ÎHigh impedance and low Coff channel output when disabled  
or deselected  
ÎLow RON: 8Ω typical  
PI2DDR3212 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.  
Î3dB Bandwidth: 3.3GHz  
ÎLow insertion loss: -0.7dB (0 ≤ f ≤ 1 GHz)  
ÎLow return loss: -23dB (0 ≤ f ≤ 1 GHz)  
It is available in a 52-pin TQFN 3.5x9mm package and 48-  
pin TFBGA 4.5x4.5mm package. e 48-pin version is pin  
compatible with CBTW28DD14.  
ÎLow cross-talk for high speed channels:  
-25dB typ. (0<f<2GHz)  
ÎLow off-isolation: -28dB (0 ≤ f ≤ 1 GHz)  
ÎLow bit-to-bit skew 20ps Max  
ÎESD: 2KV HBM  
Application  
ÎDDR3/DDR4 Memory Bus System  
ÎNVDIMM Module  
ÎPOD_12, SSTL_12, SSTL_135, SSTL_15 or SSTL_18
