Jumper Settings

DC or AC Coupled **

Jumper	DC Coupled*	AC Coupled
J7	1 & 2 SHORT	2 & 3 SHORT
J8	1 & 2 SHORT	2 & 3 SHORT
J9	1 & 2 SHORT	2 & 3 SHORT

* DC or AC Coupled: DC Coupled Is Default Setting When Delivered

** DC or AC Coupled: Note-For Sampling Rates Of 2 MSPS And Below DC Coupling Should Be Used.

Digital 3.3V Power Source

Jumper	Voltage Regulator *	Board Header **
J3	1 & 2 SHORT	OPEN
J4	1 & 2 SHORT	2 & 3 SHORT

* 3.3V Digital Power Via Voltage Regulator: Default Power Setting When Delivered

** 3.3V Digital Power Via Board Header: Not An Available Source For The ICE-PIC3T or ICE-MBT3

Analog 5V Power Source

Jumper	Board Header *	External **
J2	2 & 3 SHORT	1 & 2 SHORT

* 5V Analog Power Via Board Header: Default Power Setting When Delivered

5V power is shared between digital logic and analog logic.

** 5V Analog Power Via External Power Source:

For normal operation you will not need external power connections. Users who wish to supply the analog circuitry a "quieter" external power source, separate from the digital power connection as provided above, can connect to one or both pins of J2

a separate 5V supply.

1.) For Connecting To J2 Digi-Key Supplies a Terminal Housing.

Part Number: WM2601-ND.

2.) You Will Also Need 2 Terminals For The Housing.

Part Number: WM2200-ND

3.) Wires: 22-30 AWG.

External Clock Selection

Jumper	SMB Comparator *	User Supplied Oscillator **
J6	1 & 2 SHORT	2 & 3 SHORT

* Default Selection When Delivered.

** User Supplied Oscillator-Oscillator (X4) Should Be 5V With CMOS Output
