The internal OE pull-up is selected for this example. Refer to the device data sheet for more details on the use and external termination options of the multi-function OE pin.
Page 27 Si50x-FPB1-EVB Note that the appearance of the GUI will change based upon the device selection. Had we selected a comparable version Si502 (the dual frequency counterpart), the window would appear as follows. In this case, the Internal Resistor selection has been replaced by the OE High | OE Wk High | OE Low | Int.
Page 28 Si50x-FPB1-EVB 6. Specify Output Frequencies Since the Si503 is a four frequency device, each frequency must be specified. Output 1 is assigned a frequency of 32.768 kHz (for a clock timer application), output 2 to 12.288 MHz (for an audio clock application), output 3 to 24 MHz (for a USB application), and output 4 to 250 MHz.
Page 29 Si50x-FPB1-EVB When valid frequency selections are entered, we can proceed to the next option. At this point, if any option or parameter is not properly specified, the “Create Sample & Generate OPN” button is grayed-out and Sample Creation is not yet possible.
