DEMO MANUAL DC1532

Serial Programming
PScope has the ability to program the DC1532 board 

serially through the DC1371. There are several options 

available in the LTC2268 family that are only available 

through serially programming. PScope allows all of these 

features to be tested.
These options are available by first clicking on the Set 

Demo Board Options icon on the PScope toolbar (Figure 3).

This menu allows any of the options available for the 

LTC2268 family to be programmed serially. The LTC2268 

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
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

This will bring up the menu shown in Figure 4.
