PI3DBS3224 3.3V High Speed 2 : 4 Differential Mux/Demux Features Description ÎÎ2:4 Differential Multiplexer/Demultiplexer The PI3DBS3224 is a 2:4 bidirectional multiplexer for highspeed differential and single ended signal applications (up to 720 Mbps). The PI3DBS3224 can be used in a 1:4 or dual 1:2 multiplexer/demultiplexer configuration. The PI3DBS3224 offers a high BW of 1.2 GHz with channel RON of 13 Ω (Typ). ÎÎBidirectional Operation ÎÎCan be used in àà Single 1:4 Configuration àà Dual 1:2 Configuration àà Fan out 1:2 Configuration ÎÎHigh BW (1.2 GHz Typ) The PI3DBS3224 can also be used to fan out a differential or single ended signal pair to two ports simultaneously (fan-out configuration). The BW performance is lower in this configuration. ÎÎLow RON and CON: àà 13 Ω RON Typ àà 9 pF CON Typ ÎÎESD Performance (I/O Pins) The PI3DBS3224 operates with a 3 to 3.6V power supply. It features ESD protection of up to ±8-kV contact discharge and 2-kV Human Body Model on its I/O pins. àà ±8-kV Contact Discharge (IEC61000-4-2) àà 2-kV Human Body Model per JESD22-A114E (to GND) ÎÎESD Performance (All Pins) The PI3DBS3224 provides fail-safe protection by isolating the I/O pins with high impedance when the power supply (VCC) is not present. àà 2-kV Human Body Model per JESD22-A114E ÎÎSmall QFN package (3 x 3 mm, 0.4 mm pitch) Applications ÎÎDesktop/Notebooks Computers ÎÎDisplayPort Auxiliary Channel Multiplexing ÎÎUSB 2.0 Multiplexing ÎÎNetbooks/eBooks/Tablets 1 OUTA1 0 0 OUTA0 INA+ SAO SAI SBI SBO 1 OUTB1 1 0 OUTB0 15 SAI VCC INB- SBI 11 5 SBO 10 OUTB0- OUTB0+ OUTB1- OUTB1+ 1 SAO INB+ GND ENB 14-0061 ENA OUTA0- OUTA0+ 1 INA- 6 INB 0 16 1 ENB INA 20 ENA OUTA1- Pin Configuration OUTA1+ Block Diagram www.pericom.com04/28/14 PI3DBS3224 3.3V High Speed 2:4 Differential Mux/Demux Pin Description Pin # PIN Name I/O Type Description 14 SAI Input Control Input 15 SAO Input Control Input 12 SBI Input Control Input 11 SBO Input Control Input 16 ENA Input Enable 1 INA+ I/O Input A 2 INA- I/O Input A 10 ENB Input Enable 3 INB+ I/O Input B 4 INB- I/O Input B 9 OUTB0- I/O Output B0 8 OUTB0+ I/O Output B0 7 OUTB1- I/O Output B1 6 OUTB1+ I/O Output B1 5 GND Ground Ground 13 VCC Power Power Supply 17 OUTA0- I/O Output A0 18 OUTA0+ I/O Output A0 19 OUTA1- I/O Output A1 20 OUTA1+ I/O Output A1 14-0061 2 www.pericom.com04/28/14 PI3DBS3224 3.3V High Speed 2:4 Differential Mux/Demux Function Table ENA, ENB OUTA0 OUTA1 OUTB0 OUTB1 00 Hi-Z Hi-Z Hi-Z Hi-Z 01 Hi-Z Hi-Z - - 10 - - Hi-Z Hi-Z 11 - - - - SAI, SAO, SBI, SBO OUTA0 OUTA1 OUTB0 OUTB1 0000 INB - INA - 0001 INB - - INA 0010 INB - INB - 0011 INB - - INB 0100 - INB INA - 0101 - INB - INA 0110 - INB INB - 0111 - INB - INB 1000 INA - INA - 1001 INA - - INA 1010 INA - INB - 1011 INA - - INB 1100 - INA INA - 1101 - INA - INA 1110 - INA INB - 1111 - INA - INB 14-0061 3 www.pericom.com04/28/14 PI3DBS3224 3.3V High Speed 2:4 Differential Mux/Demux Maximum Ratings (Above which useful life may be impaired.
