3.6 ADC SYNC
Signal
The QUAD 10-bit ADC requires a SYNC signal when the internal configuration is
changed (for example Channel configuration, DMUX configuration, test mode ….). The
QUAD 10-bit Demo Kit performs this SYNC signal automatically when these modes are
changed. The SYNC signal is driven by microcontroller FX2 and the D950LV0011
devices transform the single ended signal into an LVDS signal.
Figure 3-10. ADC SYNC Signal
Note: By default, the SYNC signal via FX2 is selected but a SYNC signal via the FPGA is
allowed.
Please see Section 6.4 SYNC Signal.
3.7 DC/DC Converter The power supply for the QUAD 10-bit Demo Kit is provided by DC/DC block from Lin-
ear Technologies.
