Test Setup of DC1884 dc1884af 2 DEMO MANUAL DC1884A QUICK START PROCEDURE Setup If a DC1371 data acquisition and collection system was supplied with the DC1884, follow the DC1371 Quick Start Guide to install the required software and to connect the DC1371 to the DC1884 and to a PC. The DC1884 demonstration circuit requires up to 700mA depending on the sampling rate and the A/D converter supplied. The DC1884 should not be removed or connected to the DC1371 while power is applied. DC1884 Board Jumpers Analog Input Network The DC1884 board should have the following jumper settings as default positions (as per Figure 1): 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 70MHz, refer to the LTM9011 data sheet for a proper input network. JP14: PAR/SER: Selects Parallel or Serial Programming Mode. (Default: Serial) Optional Jumpers AJ3 and J6: Term: Enables/Disable Optional Output Termination. (Default: Removed) JP5: ILVDS: Selects Either 1.75mA or 3.5mA of Output Current for the LVDS Drivers. (Default: Removed) JP1 and JP2: Lane: Selects Either 1-Lane or 2-Lane Output Modes (Default: Removed) Note: The DC1371 does not support 1-Lane operation. JP9: SHDN: Enables and Disables the LTM9011. (Default: Removed) JP8: 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 DC1884 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 50 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 demonstration circuit. The DC1371 is used to acquire data from the DC1884. The DC1371 must first be connected to a powered USB port and have 5V applied power before applying 3.5V across the pins marked V+ and "GND" on the DC1884. DC1884 requires 3.5V for proper operation. dc1884af 3 DEMO MANUAL DC1884A QUICK START PROCEDURE Encode Clock Digital Outputs Note: Apply an encode clock to the SMA connector on the DC1884 demonstration circuit board marked "J2 CLK+." As a default, the DC1884 is populated to have a single-ended input. Data outputs, data clock, and frame clock signals are available on J1 of the DC1884. This connector follows the VITA-57/FMC standard, but all signals should be verified when using an FMC carrier card other than the DC1371. 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 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 LTM9011. 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 DC1884 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. Software The DC1371 is controlled by the PScope system software that can be downloaded from the Linear Technology website at http://www.linear.com/software/. To start the data collection software, "PScope.exe," which is installed by default to \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 DC1884 is properly connected to the DC1371, PScope should automatically detect the DC1884 and configure itself accordingly. If everything is hooked up properly and a powered and suitable 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 feature within the PScope program itself. dc1884af 4 DEMO MANUAL DC1884A QUICK START PROCEDURE Serial Programming PScope has the ability to program the DC1884 serially through the DC1371. There are several options available in the LTM9011 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 2). This will bring up the menu shown in Figure 3. This menu allows any of the options available for the LTM9011 family to be programmed serially. The LTM9011 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 and Sleep Mode. * Off (Default): Entire ADC is powered and active. Figure 2. PScope Toolbar * On: The entire ADC is powered down. Channel 1 Nap: Selects Between Normal Operation and Putting Channel 1 in Nap Mode. * Off (Default): Channel 1 is active. * On: Channel 1 is in nap mode. Channel 2 Nap: Selects Between Normal Operation and Putting Channel 2 in Nap Mode. * Off (Default): Channel 2 is active. * On: Channel 2 is in nap mode. Channel 3 Nap: Selects Between Normal Operation and Putting Channel 3 in Nap Mode. * Off (Default): Channel 3 is active. * On: Channel 3 is in nap mode. Channel 4 Nap: Selects Between Normal Operation and Putting Channel 4 in Nap Mode. * Off (Default): Channel 4 is active. * On: Channel 4 is in nap mode. Figure 3.
