Refer to Figure 1 for proper measurement equipment setup and follow this procedure. Setup If a DC1371 QuikEval™ II Data Acquisition and Collection System was supplied with the DC1525A demonstration circuit, follow the DC1371 Quick Start Guide to install the required software and for connecting the DC1371 to the DC1525A and to a PC. DC1525A Demonstration Circuit Board Jumpers The DC1525A demonstration circuit board should have the following jumper settings as default positions: (as per Figure 1). J13: PAR/SER: Selects Parallel or Serial programming mode. (Default – Serial) J14: LANE: Selects either 1 lane or 2 lane output modes (Default – Removed) NOTE: The DC1371 does not support 1 lane operation. J15: SHDN: Enables and disables the LTC2175. (Default – Removed) J2: WP: Enable/Disables write protect for the EEPROM. (Default – Removed) Note: optional jumper should be left open to ensure proper serial configuration. Applying Power and Signals to the DC1525A Demonstration Circuit The DC1371 is used to acquire data from the DC1525A, the DC1371 must FIRST be connected to a powered USB port and have equal to 5V applied power BEFORE applying 3.6V to 6V across the pins marked V+ and GND on the DC1525A. DC1525A requires 3.6V for proper operation. J8: Term: Enables/Disable optional output termination. (Default – Removed) Regulators on the board produce the voltages required for the ADC. The DC1525A demonstration circuit requires up to 500mA depending on the sampling rate and the A/D converter supplied. J5: ILVDS: Selects either 1.75mA or 3.5mA of output current for the LVDS drivers. (Default – Removed) The DC1525A should not be removed, or connected to the DC1371 while power is applied.

DC1525A Setup Analog Input Network For optimal distortion and noise performance the RC network on the analog inputs may need to be optimized for different analog input frequencies. For input frequencies above 140MHz, refer to the LTC2175 data sheet for a proper input network. Other input networks may be more appropriate for input frequencies less that 5MHz. In almost all cases, filters will be required on both analog input and encode clock to provide data sheet SNR. The filters should be located close to the inputs to avoid reflections from impedance discontinuities at the driven end of a long transmission line. Most filters do not present 50Ω outside the passband. In some cases, 3dB to 10dB pads may be required to obtain low distortion. If your generator cannot deliver full-scale signals without distortion, you may benefit from a medium power amplifier based on a Gallium Arsenide Gain block prior to the final filter. This is particularly true at higher frequencies where IC based operational amplifiers may be unable to deliver the combination of low noise figure and High IP3 point required. A high order filter can be used prior to this final amplifier, and a relatively lower Q filter used between the amplifier and the demo circuit. Apply the analog input signal of interest to the SMA connectors on the DC1525A demonstration circuit board marked J3 AIN1, J4 AIN2, J6 AIN3, J7 AIN4. These inputs correspond with channels 1 to 4 of the ADC respectively. These inputs are capacitive coupled to Balun transformers ETC1-1-13. Encode Clock NOTE: Apply an encode clock to the SMA connector on the DC1525A demonstration circuit board marked J11 CLK+. As a default the DC1525A is populated to have a single-ended input. For the best noise performance, the ENCODE INPUT must be driven with a very low jitter, square wave source. The amplitude should be large, up to 3VP-P or 13dBm. When dc1525af 3 DEMO MANUAL DC1525A QUICK START PROCEDURE 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 Agilent 8644B generators are used for both the Clock input and the Analog input. 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. Digital Outputs Data outputs, data clock, and frame clock signals are available 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. Figure 3. PScope Toolbar Software The DC1371 is controlled by the PScope™ System Software provided or downloaded from the Linear Technology website at http://www.linear.com/software/. To start the data collection software if PScope.exe is installed (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 suitable convert clock is present, clicking the Collect button should result in time and frequency plots displayed in the PScope window.
