Table 2. List of Standalone Jumpers (continued)
Default
Jumper Position Jumper Description
JMP16 Installed When installed, shorts HPLCOM_A and HPRCOM_A. Use only if these signals are set to constant VCM and external feedback.
Also, switch SW1 must be in the "Capless" position when installed.
JMP17 Open When installed, shorts across the output capacitor on HPRCOM_A; remove this jumper if using AC-coupled output drive.
JMP18 Open Selects on-board EEPROM as Firmware Source. Note that for this EVM the Firmware Source EEPROM is on the USB-MODEVM.
JMP19 Installed When installed, allows the USB-MODEVM to hardware reset the device under user control
JMP20 Installed When installed, shorts HPLCOM_B and HPRCOM_B. Use only if these signals are set to constant VCM and external feedback.
JMP21 Open When installed, shorts across the output capacitor on HPRCOM_B; remove this jumper if using AC-coupled output drive.

J17A
Default
Signals Position Jumper Description
BCLK_A pin 3 - pin 5 Connects Block A BCLK_A and Block B BLCK_B together for ease of evaluation. When Block A and Block B use different digital
and clocks/data this jumper MUST be removed.
BCLK_B
WCLK_A pin 7 - pin 9 Connects Block A WCLK_A and Block B WLCK_B together for ease of evaluation. When Block A and Block B use different
and digital clocks/data this jumper MUST be removed.
WCLK_B
DIN_A pin 10 - pin Connects Block A DIN_A and Block B DIN_B together for ease of evaluation. When Block A and Block B use different digital
and 11 clocks/data this jumper MUST be removed.
DIN_B
DOUT_A open Connects Block A DOUT_A and Block B DOUT_B together for ease of evaluation. When Block A and Block B use different
and digital clocks/data this jumper MUST be removed. Also if both Block A and Block B are used together this jumper must be
DOUT_B removed due to potential conflict on the DOUT signals.
MCLK_A pin 17 - pin Connects Block A MCLK_A and Block B MCLK_B together for ease of evaluation. When Block A and Block B use different
and 19 digital clocks/data this jumper MUST be removed..
MCLK_B
The Block A analog inputs to the EVM can be connected through the analog headers J1, J2, J3, J4, J5,
and J6 around the edge of the board. The connection details of each header/connector can be found in
Table A-2 .
The Block A analog outputs to the EVM can be connected through J7, J8, J9, J11,and J12 at the edges of
the board. The connection details can be found in Table A-2 .
The digital inputs and outputs of the EVM can be monitored through J16 and J17. If external signals need
to be connected to the EVM, digital inputs should be connected via J14 and J15 on the USB-MODEVM
and the SW2 switch should be changed accordingly (see Section 2.2.1 ). The connector details are
available in Section A.2 .
