VERSACLOCK 6 - 5P49V6901 Evaluation Board Table 1: 5P49V6901 EBV Pins and Functions Item Name On-Board Connector Function Label 1 Output 0 J3 Single ended buffered output of input reference clock 4-way header to select a power supply method for outputs 0, 1, 2, 3 Output Voltage Power 2 JP2, JP4, JP6, JP13, JP8 and 4. The center pin is the output voltage. Use the jumper to select Supply Selector 3.3V, 2.5V, 1.8V or VDDO J supply. VDDO J is the voltage from J16 3 CLKIN S J1 SMA Pair used to monitor differential input CLKIN with CLKINB S 4 Clock Input J2/J4 Used as primary differential clock input Used as primary single ended clock input. Maximum full swing 5Xin J6 limited to 1.2V 6 Aardvark Connector JP1 For Aardvark connection 7 Interface Mode Selector JP11/JP12 Used to select either I2C mode or Hardware select mode 8 Input Voltage Regulator GND/USB 5V Used to input 5V supply in hardware select mode Used for connection with a PC and for interaction with the IDT Timing 9 USB Interface J18 Commander Software. Can be one differential output pair or two individual single ended 10 Output 1 J7/J8 outputs Can be one differential output pair or two individual single ended 11 Output 2 J10/J9 outputs Used for grounding. If J15 and/or J16 is used for power supply, this 12 Ground Jack J17 jack functions as the power return. Can be one differential output pair or two individual single ended 13 Output 3 J13/11 outputs Input Voltage Power Supply Provides selection of VDDA VDDD supply from regulators or 14 JP3 Selector VDDD J supply from J16 15 Output Voltage Jack J15 Connect 3.3V, 2.5V or 1.8V for the output voltage of the device 16 Power Supply Jack J16 Connect 3.3V power supply for the core voltage of the device S1: Output Enable(OE/SD) S2: Sel0 17 DIP Switch U2 S3: Sel1 S4: CLKSEL S8: Sel 1:0 Default: I2C mode Can be one differential output pair or two individual single ended 18 Output 4 J12/14 outputs 2 REVISION A 09/17/15
