Product Description

The PI2DBS212 is an 1:2 differential channel multiplexer/demultiplexer switch. Using a specialized design scheme, Diodes has been able to achieve a performance of 3Gbps data rate mux/de-mux function. Due to its bi-directional nature, the PI2DBS212 can be used to allocate bandwidth to two different locations as a demux, or connect two high-speed sources to a single receiver as a mux.

The PI2DBS212 will target the following standards: SAS, SATA I, SATA II, XAUI, INFINIBAND, HYPERTRANSPORT, and RAP ID I/O, for application in computers, consumer electronics, instrumentation, etc.


  • SAS, SATA2, XAUI Switch
  • 2 Differential Channel, 2:1 Mux/DeMux
  •  Bandwidth of 2.0 GHz (–3dB)
  • Low Bit-to-Bit Skew : <5 ps
  • Low Crosstalk: –26dB @ 3.2 Gbps
  • Low Off Isolation: –35dB @ 3.2 Gbps
  • VDD Voltage: 1.2V to 1.8V ±10%
  • ESD Tolerance: 8kV HBM I/O, 2kV HBM select pin
  • Packaging (Pb-free & Green): – 28-Contact TQFN
