Full Scale Adjust pin : ‘1’ sets FS =
Interlaced or parallel output mode. (only in Dual Port mode
operation) HIGH = data arrives in channel A at falling edge of clock
and data arrives in channel A at rising edge of clock. LOW = data
arrives in channels A and B at rising edge of clock.
Output Mode select. Low = Dual Port, CMOS; High = LVDS
Data format select. Low = Binary, High = Two’s compliment
3.3V analog supply. (3.0V to 3.6V)
Analog Ground
Control Pin for Reference , Full Scale
1.235 Reference I/O - function dependent on REFSENSE
Analog input – true.
Analog input – compliment.
Data sync (input) – true. Aligns output channels so that data from
channel A represents a sample that is prior from data in channel B,
taking into account the pipeline delay. (See timing diagram). Tie
LOW if not used.
Data sync (input) – compliment. Tie HIGH if not used.
Clock input – true.
Clock input – compliment.
