JP14 and JP16 for SEL0/1 After programming multiple configurations, the 5P49V6965/6975 can be restarted in Hardware Select mode and then the SEL0 and SEL1 pins can be used to select a configuration.
® VersaClock 6E – 5P49V6965 and 5P49V6975 Programmer Board User Guide JP12 and JP13 Functionality JP12 controls the CLKSEL pin and JP13 controls the SD/OE pin on the 5P49V6965/6975. These pins have pull-down resistors on the chip so when the pins are left open, the pins will be pulled low. When placing a jumper, the pin will be pulled high. This way the functionality of the CLKSEL and SD/OE pins can be verified.
® VersaClock 6E – 5P49V6965 and 5P49V6975 Programmer Board User Guide JP1 and JP5 Functionality JP5 is the CLK0 output (OUT0) of the 5P49V6965/6975. The upper pin is ground and the lower pin is the actual output. Connect a probe between the upper (GND) and lower (OUT0) pins to measure the OUT0 frequency or waveform.
® VersaClock 6E – 5P49V6965 and 5P49V6975 Programmer Board User Guide J2 and J3 Functionality J2 and J3 are SMA footprints for an alternative differential connection to OUT1. The default programmer board does not have these connectors assembled. Figure 9. J2 and J3 Alternative CLK1 (OUT1) JP3, JP4, JP6 and JP8 Functionality The default programmer board does not have jumper pins assembled for JP3, JP4, JP6 and JP8.
® VersaClock 6E – 5P49V6965 and 5P49V6975 Programmer Board User Guide Configuration and Setup Use the following steps to setup the 5P49V6965 or 5P49V6975 device using USB-to-I2C and start the configuration. 1. Before connecting the programmer board to USB, make sure JP1 is open (no jumper). Also see JP1 functionality and Figure 7. 2.
