Jumper Description

Designator Type Position

W1 2-pin Soldered Provides +3.3VA voltage source to AVDD input pin 10 of ADC3101.

W2 2-pin Soldered Provides IOVDD voltage source to IODD input pin 21 of ADC3101.

W3 2-pin Soldered Provides +1.8VD voltage source to DVDD input pin 22 of ADC3101.

W4 2-pin Installed Enables audio connector J9 input to IN1L(P) - pin 8 of ADC3101.

W5 2-pin Installed Enables audio connector J9 input to IN1R(M) - pin 11 of ADC3101.

W6 3-pin 1–2 Input DMCLK (1–2) or GPIO0 (2–3) to pin 20 of ADC3101.

W7 3-pin 1–2 Input DMDIN (1–2) or GPIO1 (2–3) to pin 19 of ADC3101.

W8 3-pin 2–3 Selects IOVDD voltage source (1–2 selects 1.8 V and 2–3 selects 3.3 V).

W9 2-pin Not Installed Use GPIO1.

W10 2-pin Not Installed Enable hardware reset if available.

W11 2-pin Not Installed When not installed, selects USB-MODEVM EEPROM as firmware source. When installed, selects onboard

EEPROM as firmware source.

W12 2-pin Installed When installed, enables MICBIAS1 to left microphone (MK1).

W13 2-pin Installed When installed, enables MICBIAS2 to right microphone (MK2).

2.3 Analog Signal Connections

2.3.1 Analog Inputs

The analog input sources can be applied directly to terminal blocks J6, J7, and J8 or input jack J9. The

connection details can be found in Appendix A.

2.4 Digital Signal Connections

The digital signals (BCLK, WCLK, DOUT, and MCLK) can be monitored via J5. If external digital signals

are connected to the EVM, these digital inputs must be connected via J14 on the USB-MODEVM, and the

SW2 switch must be changed accordingly (see Section 2.2.1). The connector details are available in

Section A.2.

2.5 Power Connections

The TLV320ADC3101EVM can be powered independently when being used in stand-alone operation or

by the USB-MODEVM when it is plugged onto the motherboard.
