Figure 19. Input/Output Circuit Based on the AD7869
LK 5, ADC Internal Clock Selection
T his link configures the ADC for continuous or noncontinuous
internal clock operation.
LK 6, DAC Updating
T he DAC,
LDAC
input may asserted independently of the
ADC
CONVST
signal or it may be tied to
CONVST
or it may
tied to GND.
LK 7, ADC Clock Source
T his link provides the option for the ADC to use its own inter-
nal clock oscillator or an external T T L compatible clock.
LK 8 Frame Synchronous Option
LK 8 provides the option of tying the ADC
RFS
output to the
DAC
TFS
input.
LK 9 T ransmit/Receive Clock Option
LK 9 provides the option to connect the ADC RCLK to the
DAC T CLK .
