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.

JP3, JP4, JP6 and JP8 Functionality
The default programmer board does not have jumper pins assembled for JP3, JP4, JP6 and JP8. The two pins in each jumper are
shorted on the board with a 0 ohm resistor. The lower pins are connected to a 3.3V power regulator on the board. The upper pins are
each connected to a different VDDO pin. So the programmer board connects each VDDO pin to 3.3V by default. This is sufficient when
programming 5P49V6965 or 5P49V6975 devices and checking output frequencies. Jumper pins can be installed and the 0 ohm resistors
can be removed to gain control of the VDDO pins. A jumper can be placed to connect to the on-board 3.3V regulator. Remove the jumper
and connect the upper pin to an external power supply, in case a different voltage is needed. The ground side of the power supply can be
connected to the GND point on the right.

VC6E Programmer Board Compatibility
The VC6E programmer board hardware was designed for the 5P49V6965 and 5P49V6975 but is backwards compatible with older VC6
and VC5 devices. Essentially, this VC6E programmer board can do everything and more than the older VC5 programmer board.
This VC6E programmer board can be used with the following devices:
▪
Using the VC6E Timing Commander personality: 5P49V6965 and 5P49V6975.
▪
Using the VC6 Timing Commander personality: 5P49V6901, 5P49V6913 and 5P49V6914.
▪
Using the VC5 Timing Commander personality: 5P49V5901, 5P49V5913, 5P49V5914, 5P49V5923, 5P49V5925, 5P49V5927,
5P49V5929, 5P49V5933 and 5P49V5935.
This VC6E Programmer Board User Guide will only deal with the VC6E Timing Commander personality.
