The TS3DDR4000 is 1:2 or 2:1 high speed DDR2/DDR3/DDR4 switch that offers 12-bit wide bus switching. The A port can be switched to the B or C port for all bits simultaneously. Designed for operation in DDR2, DDR3 and DDR4 memory bus systems, the TS3DDR4000 uses a proprietary architecture that delivers high bandwidth (single-ended –3dB bandwidth at 5.6 GHz), low insertion loss at low frequency, and very low propagation delay. The TS3DDR4000 is 1.8 V logic compatible, and all switches are bi-directional for added design flexibility. The TS3DDR4000 also offers a low-power mode, in which all channels become high-Z and the device consumes minimal power.
