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

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.
