PRODUCTION DATA
The LVDS output buses can be configured to demux the output data from each ADC channel by one or two by setting the LDEMUX parameter. When a demux-by-2 option is selected (LDEMUX = 1), the number of output strobes and data clocks can be reduced by using LCS_EN. The two channels of the ADC12DL3200 can be interleaved together to achieve double the sample rate (that is, single-channel mode) by setting DES_EN to 1. Table 7-11 lists the available interface and configuration modes. When the LSB replacement with strobe option is used (SYNC_PAT = 0x2), the strobe column of Table 7-11 can be ignored and replaced with 0 because all dedicated strobe outputs can be disabled.
