Configuring for CMOS CNV Mode
The hardware changes required to operate in CMOS CNV mode
are as follows:
Remove the 100 Ω termination resistor (RTCNV).
►
Populate R38 with a 0 Ω resistor to tie CNV− to GND.
►
Then both the AD4080 and
►
CMOS input and output mode, respectively, as follows:
The AD4080 must be configured to accept CMOS level CNV
►
signaling. Refer to the LVDS_CNV_EN bit in the ADC_DA-
TA_INTF_CONFIG_B register (Register 0x16, Bit 0) in the
AD4080 data sheet for additional details.
The AD9508 OUT2 channel must then be reconfigured for
►
CMOS level signaling. Refer to Register 0x1F (OUT1 driver)
and Register 0x20 (OUT1 CMOS) of the AD9508 data sheet
for further detail on configuring the output drivers.
