Description
Type Designator
J9/J10 External CW Mode clock. The default is using onboard oscillator.
CW output for I-channel via an external operational amplifier. The EVM has converted the
differential signal CW_IP_OUTP and CW_IP_OUTM into this single-ended output through an
J12
operational amplifier.
JP52/JP53
To observe CW_IP_OUTP and CW_IP_OUTM before the external operational amplifier, the user
can probe JP52 and JP53.
CW Mode
CW output for V-channel via an external operational amplifier. The EVM has converted the
differential signal CW_VP_OUTP and CW_VP_OUTM into this single-ended output through an
J13
operational amplifier.
JP56/JP57
To observe CW_VP_OUTP and CW_VP_OUTM before the external operational amplifier, the user
can probe JP56 and JP57.
JX1 This connector allows the user to see signals of J12 and J13 simultaneously.
JP9 selects on_board_ADC CMOS clock or external clock from J14. Default setup in Figure 4 uses
onboard CMOS clock. Set it to the other side to use the external clock source.
JP9/JP10
ADC
Short to power up onboard CMOS clock.
J14 External ADC clock Input.
