4•3•3 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).

4•3•4 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.

NOTE

Should be taken into consideration that 12V external power input for Flash SIMM have no protection.

Factory Set

4•3•5 JP5,JP8 - 600 Ohm Termination.

Set for audio measurements. Factory set - JP5,JP8 are OPEN.

4•3•6 JP6,JP7 - MIC Enable.

Set if using external microphone audio source. Factory set - JP6,JP7 are CLOSE.

4•3•7 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 below:
