1 / 10 page 1 PS8921A 10/31/07 Features • 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: +1.8V • ESD Tolerance: 8kV HBM I/O, 2kV HBM select pin • Packaging (Pb-free & Green): – 20-Lead QSOP – 28-Contact TQFN 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-direc- tional 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 reciever 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-Lead QSOP PI2DBS212 1.8V, 1.8GHz, Differential Broadband Signal Switch, 2-Differential Channel, 2:1 Mux/DeMux Switch, w/ Single Enable 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 1 2 3 4 5 6 7 8 9 10 24 23 22 21 20 19 18 17 16 15 11 12 13 14 28 27 26 25 GND NC SEL A0+ A0- A1+ A1- NC VDD GND B0+ B0- B1+ B1- GND VDD C0+ C0- C1+ C1- 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 GND SEL VDD A0+ A0- A1+ A1- VDD VDD GND B0+ B0- B1+ B1- GND VDD C0+ C0- C1+ C1- 07-0243 |
