DEMO MANUAL DC1525A

using a sinusoidal signal generator a squaring circuit can

be used. Linear Technology also provides demo board

DC1075A that divides a high frequency sine wave by four,

producing a low jitter square wave for best results with

the LTC2175.

Using bandpass filters on the clock and the analog input

will improve the noise performance by reducing the

wideband noise power of the signals. In the case of the

DC1525A a bandpass filter used for the clock should be

used prior to the DC1075A. Data sheet FFT plots are taken

with 10 pole LC filters made by TTE (Los Angeles, CA) to

suppress signal generator harmonics, non-harmonically

related spurs and broadband noise. Low phase noise Agi-

lent 8644B generators are used for both the Clock input

and the Analog input.

Digital Outputs

Data outputs, data clock, and frame clock signals are avail-

able on J1 of the DC1525A. This connector follows the

VITA-57/FMC standard, but all signals should be verified

when using an FMC carrier card other than the DC1371.

Software

The DC1371 is controlled by the PScope™ System Soft-

ware provided or downloaded from the Linear Technology

website at http://www.linear.com/software/.

To start the data collection software if PScope.exe is in-

stalled (by default) in \Program Files\LTC\PScope\, double

click the PScope Icon or bring up the run window under

the start menu and browse to the PScope directory and

select PScope.

If the DC1525A demonstration circuit is properly connected

to the DC1371, PScope should automatically detect the

DC1525A, and configure itself accordingly.

If everything is hooked up properly, powered and a suit-

able convert clock is present, clicking the Collect button

should result in time and frequency plots displayed in

the PScope window. Additional information and help for

PScope is available in the DC1371 Quick Start Guide and in

the online help available within the PScope program itself.

Serial Programming

PScope has the ability to program the DC1525A board

serially through the DC1371. There are several options

available in the LTC2175 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 Bd Options icon on the PScope toolbar (Figure 3).

This will bring up the menu shown in Figure 4.

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

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.
