LK5, ADC Internal Clock Selection
This link configures the ADC for continuous or noncontinuous
internal clock operation.
LK6, DAC Updating
The DAC, LDAC input may asserted independently of the
ADC CONVST signal or it may be tied to CONVST or it may
tied to GND.
LK7, ADC Clock Source
This link provides the option for the ADC to use its own inter-
nal clock oscillator or an external TTL compatible clock.
LK8 Frame Synchronous Option
LK8 provides the option of tying the ADC RFS output to the
DAC TFS input.
