PI2DDR3212 1.35V/ 1.5V/1.8V 14 bit 2:1 DDR3/DDR4 Switch Features Description 14 bit 2:1 switch that supports DDR3 800 2133Mbps, DDR4 This 14-bit DDR3/DDR4 switch is designed for 1.35V/ 1.5V/ 1600~4266 Mbps 1.8V supply voltage, POD 12, SSTL 135, SSTL 15 or SSTL 18 VDD 1.35V/ 1.5V/ 1.8V signaling and CMOS select input signals. It is designed for DDR3 or DDR4 memory bus with speed up to 5Gbps. It Flow through pinout option for easy layout supports DDR3 800 2133Mbps and DDR4 1600~4266 Mbps. SEL and Global Enable PI2DDR3212 has a 1:2 demux or 2:1 mux topology. All 14-bit 110 A typ. operating current at 1.35V VDD. channels can be switched to one of the two ports simultaneously High impedance and low Coff channel output when disabled with the SEL input. This device also allows all ports to be or deselected disconnected. Low R : 8 typical PI2DDR3212 uses Pericoms proprietary high speed switch ON 3dB Bandwidth: 3.3GHz technology providing consistent high bandwidth across all channels, with very little insertion loss, cross-talk, and bit to bit Low insertion loss: -0.7dB (0 f 1 GHz) skew. Low return loss: -23dB (0 f 1 GHz) It is available in a 52-pin TQFN 3.5x9mm package and 48- Low cross-talk for high speed channels: pin TFBGA 4.5x4.5mm package. The 48-pin version is pin -25dB typ. (0<f<2GHz) compatible with CBTW28DD14. Low o-ff isolation: -28dB (0 f 1 GHz ) Low bit-to-bit skew 20ps Max Application DDR3/DDR4 Memory Bus System ESD: 2KV HBM NVDIMM Module POD 12, SSTL 12, SSTL 135, SSTL 15 or SSTL 18 signaling Flash Memory Array sub system Packaging (Pb-free and Green) High Speed multiplexing 52 pin TQFN (3.5x9mm) 48 pin TFBGA (4.5x4.5mm)pin compatible with Pin Configuration (52-pin TQFN) CBTW28DD14 Pin Configuration (48 pin TFBGA ) GND 1 47 B11 EN 2 46 C11 3 45 A13 B10 4 44 A12 C10 5 43 A11 B9 42 VDD 6 C9 41 A10 7 B8 A9 8 40 C8 A8 9 39 B7 A7 10 38 C7 GND 11 37 V DD A6 12 36 B6 13 35 A5 C6 14 34 A4 B5 33 A3 15 C5 32 VDD 16 B4 A2 17 31 C4 A1 18 30 B3 A0 19 29 C3 SEL 20 28 B2 GND 21 27 C2 www.pericom.com 10/23/14 14-0169 1 C0 22 52 B13 B0 23 51 C13 C1 24 50 B12 B1 25 49 C12 GND 26 48 GNDPI2DDR3212 1.35V/ 1.5V/1.8V 14 bit 2:1 DDR3/DDR4 Switch Block Diagram A0 B0 A1 B1 A2 B2 A3 B3 A4 B4 A5 B5 A6 B6 A7 B7 A8 B8 A9 B9 A10 B10 A11 B11 A12 B12 A13 B13 C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 C12 C13 SEL LOGIC CONTROL EN Application Supercapacitor NVDIMM Application using PI2DDR3212 SSD, Flash storage application using PI2DDR3212 www.pericom.com 10/23/14 14-0169 2
