JP3 - 50 Ohm Enable.
JP3 provides 50 Ohm resistance termination in case when using an external clock source via
coaxial cable connected to the SMB CLOCKIN. In so doing the on-board clock oscillator U18 must
be removed from the socket. Default set is JP3-OPEN (termination disable).

JP4 - VPP Source Selector
JP4 selects the source for VPP - programming voltage for the Flash SIMM. When a jumper is
located between pins 1 - 2 of JP4 (Factory Set), the VPP is connected to the 5V0 plane of the ADS.
For 12V programming set VPP will be drawn from external power supply 12V connected to pins
JP4/2,3.

JP9 - 5V power supply for CODEC
JP9 selects the source for CODEC Power Rail. When a jumper is located between pins 1 - 2 of
JP9 (Factory Set), the CODEC feeds from the 5V0 plane of the ADS. When a jumper is removed
external low noise power supply 5V @ 200 mA might be connected to JP9 pins 2,3. See figure
