3 Description
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.
