QUICK START PROCEDURE
This menu allows any of the options available for the
LTC2175 family to be programmed serially. The LTC2175
family has the following options:
Randomizer: Enables Data Output Randomizer
• Off (Default): Disables data output randomizer
• On: Enables data output randomizer
Two's Complement: Enables two's complement mode
• Off (Default): Selects offset binary mode
• On: Selects two's complement mode
Sleep Mode: Selects between normal operation, sleep
mode:
• Off (Default): Entire ADC is powered, and active
• On: The entire ADC is powered down.
Channel 1 Nap: Selects between normal operation and
putting channel 1 in nap mode.
• Off (Default): Channel one is active
• On: Channel one is in nap mode
Channel 2 Nap: Selects between normal operation and
putting channel 2 in nap mode.
• Off (Default): Channel two is active
• On: Channel two is in nap mode
Channel 3 Nap: Selects between normal operation and
putting channel 3 in nap mode.
• Off (Default): Channel three is active
• On: Channel three is in nap mode
DEMO MANUAL DC1525A
Channel 4 Nap: Selects between normal operation and
putting channel 4 in nap mode.
• Off (Default): Channel four is active
• On: Channel four is in nap mode
Output Current: Selects the LVDS output drive current
• 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
• Off (Default): Disables internal termination
• On: Enables internal termination
Outputs: Enables Digital Outputs
• Enabled (Default): Enables digital outputs
• Disabled: Disables digital outputs
Test Pattern: Selects Digital output test patterns. The
desired test pattern can be entered into the text boxes
provided.
• Off(default): ADC input data is displayed
• On: Test pattern is displayed.
Once the desired settings are selected hit OK and PScope
will automatically update the register of the device on the
DC1525A demo board.
