Description

Pericom Semiconductor’s PI2DBS212 is an 1:2 differential channel multiplexer/demultiplexer switch. Using a specialized design scheme, Pericom has been able to achieve a performance of 3Gbps data rate mux/de-mux function. Due to its bi-direction- al 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. Block Diagram Pin Description - 20-Pin QSOP PI2DBS212 2.0GHz, Differential Broadband Signal Switch, 2-Differential Channel, 2:1 Mux/DeMux Switch Truth Table Function SEL Port A to Port B L Port A to Port C H SEL A1- A1+ A0- A0+ B0- B0+ B1+ C0+ B1- C0- C1+ C1- Pin Description - 28-Contact TQFN 11 12 13 14 28 27 26 25GND NC SEL A0+ A0- A1+ A1- NC VDD GND B0+ B0- B1+ B1- GND VDD C0+ C0- C1+ C1- VDD GND VDD GND VDD GND VDD GND GND SEL VDD A0+ A0- A1+ A1- VDD VDD GND B0+ B0- B1+ B1- GND VDD C0+ C0- C1+ C1- 09-0008
