Figure 4: Demobd Configuration Options.
This menu allows any of the options available for the
LTC2261-14 family to be programmed serially. The
LTC2261-14 family has the following options:
Power Control:
Selects between normal operation, nap
and sleep modes.
• Normal (Default) – Entire ADC is powered, and active.
• Nap – ADC core powers down while references stay
active.
• Shutdown – The entire ADC is powered down.
Clock Inversion:
Selects the polarity of the CLKOUT signal:
• Normal (Default) – Normal CLKOUT polarity
• Inverted – CLKOUT polarity is inverted
Clock Delay:
Selects the phase delay of the CLKOUT signal:
• None (Default) – No CLKOUT delay
• 45° – CLKOUT delayed by 45°
• 90° – CLKOUT delayed by 90°
• 135° – CLKOUT delayed by 135°
Clock Duty Cycle:
Enables or disables Duty Cycle Stabilizer.
• Stabilizer off (Default) – Duty Cycle Stabilizer disabled
• Stabilizer on – Duty Cycle Stabilizer enabled
Output Current:
Selects the LVDS output drive current.
This option is not used on the FT1370.
• 1.75mA (Default) - LVDS output driver current
• 2.1mA - LVDS output driver current
• 2.5mA - LVDS output driver current
• 3.0mA - LVDS output driver current
• 3.5mA - LVDS output driver current
• 4.0mA - LVDS output driver current
• 4.5mA - LVDS output driver current
Internal Termination:
Enables LVDS internal termination
This option is not used on the FT1370.
• Off (Default) – Disables internal termination
• On – Enables internal termination
Outputs:
Enables Digital Outputs.
• Enabled (Default) – Enables digital outputs
• Disabled – Disables digital outputs
