QUICK START PROCEDUREDC2085 is easy to set up to evaluate the performance of the LTC2000. Refer to Figure 1 for proper measurement equip-ment set-up and follow the procedure below:

Setup

If the Altera Stratix IV GX FPGA Development Kit was not supplied with the DC2085 demonstration circuit, follow the Altera Stratix IV demo manual to install the required software and for connecting the Altera Stratix IV to the DC2085 and to a PC.

QUICK START PROCEDUREHARDWARE SETUP

SMAs

J2 & J3: Differential Trigger Input. Apply a signal to J2 from a 50Ω driver. Absorptive filters are required for data sheet performance. Use J2 and J3 if the trigger is a differential signal.

J4: Sample Clock Input. Apply a clock signal to this SMA connector from a 50Ω driver. A 0dBm clock source should be sufficient, but for best phase noise and jitter performance, use the highest possible amplitude and slew rate, up to 15dBm.

J5 & J6: Differential Output Signals. These SMAs provide access to the differential outputs of the DAC. The output impedance is designed to be 50Ω at each SMA, or 100Ω differential. Connect an external balun or combiner to these pins to drive a single-ended spectrum analyzer. Linear Technology has various coupon boards for specific frequencies and applications. More information is available at www.linear.com.

J8: SYNC. This SMA is to provide access to the sync pin of the LT8614. It is not used in normal use.

Turrets

+5V: Positive Input Voltage for the DAC and Digital Circuits. This voltage feeds a series of regulators that supply the proper voltages for the DAC. The voltage range for this turret is 4.8V to 5.2V. Note: For close-in phase noise plots, driving this voltage is not ideal. There is a known 20kHz noise hump in the spectrum that is generated by the regulators. For the best phase noise performance, back drive the onboard regulators with the provided turrets from a low noise supply.

GND: Ground Connection. This demo board has only a single ground plane. This turret should be tied to the GND terminal of the power supply being used.

SVDD3V0: Optional 3.0V Input. This pin is connected directly to the SVDD pin of the DAC. It requires a supply that can deliver up to 100mA. Driving this pin will shut down the onboard regulator.

AVDD3V3: Optional 3.3V Input. This pin is connected directly to the AVDD3V3 pin of the DAC. It requires a

supply that can deliver up to 200mA. Driving this pin will shut down the onboard regulator.

DVDD3V3: Optional 3.3V Input. This pin is connected directly to the DVDD3V3 pin of the DAC. It requires a supply that can deliver up to 50mA. Driving this pin will shut down the onboard regulator.

AVDD1V8: Optional 1.8V Input. This pin is connected directly to the AVDD1V8 pin of the DAC. It requires a supply that can deliver up to 1A. Driving this pin will shut down the onboard regulator.

DVDD3V3: Optional 1.8V Input. This pin is connected directly to the DVDD1V8 pin of the DAC. It requires a supply that can deliver up to 500mA. Driving this pin will shut down the onboard regulator.

VP1: This is a test point that is at the output of the on-board switching regulator. It is meant for test purposes. It can also be driven to 2.5V to shut down the output of the switching regulator.

TSTP & TSTN: These pins are tied directly to the TSTP and TSTN pins of the DAC. They can be used to measure the internal temperature and timing of the LVDS inputs.

FSADJ: This is an optional pin that is tied directly to the FSADJ pin of the DAC. It can be used to set the full-scale output current of the DAC. In normal operation this pin is tied to GND through 500Ω to set a current of 40mA at the output.

REFIO: This pin is tied directly to the REFIO pin of the DAC and is used to set the reference voltage for the DAC. Normally it is internally set to 1.25V but can be overdriven with an external voltage from 1.1V to 1.4V.

Jumpers

The DC2085 demonstration circuit should have the fol-lowing jumper settings as default positions.

JP1: PD. In the RUN position this pin results in normal operation of the DAC. In the SHDN position the DAC is powered down. (Default: RUN or up)

JP2: SPI and JTAG. This jumper selects how the FPGA is programmed. In the SPI position the FPGA is programmed from the onboard FTDI chip and the LTDACGen software. In

http://www.linear.com

4dc2085afb

DEMO MANUAL DC2085

the JTAG position the J9 is used with a JTAG programmer to program the FPGA. (Default: SPI or down)

Connectors

J1: DC590. This is an optional header that can be used to program the DAC with the DC590. (Default: removed)

J9: JTAG. This is an optional header that can be used to program the FPGA through a JTAG programmer. (Default: removed)

J7: USB. Connect a USB cable from J7 to a computer with the LTDACGen software installed.

J10 & J11: HSMC Connectors. These connectors are designed to connect to the Altera Stratix IV development board. All of the communication between the FPGA and the DAC is routed through these connectors.

APPLYING POWER AND SIGNALS TO THE DC2085 DEMONSTRATION CIRCUIT

If a Stratix IV demo board is used to supply data to the DC2085, the two boards should first be bolted together

and a proper connection should be made. If Linear Tech-nology provided the Stratix IV board the proper bit file is already installed in flash memory and will begin to operate when the board is powered on. If an unprogrammed FPGA board is used, refer to the appropriate documentation on how to program it.

Power should be applied to the system in this order:

1. Connect the Altera board to the provided power supply.

2. Connect the USB cable to J7.

3. Apply a clock to J4.

4. Connect any optional output board to J5 and J6.

5. Turn on the voltage to the Altera board.

6. Connect the 5V from a bench supply to the +5V turret on the DC2085.

7. Open the LTDACGen software and hit connect.

LTDACGen should report back that it is connected to the FPGA. See Figure 2:

QUICK START PROCEDUREANALOG OUTPUT NETWORK

The analog output network of the DC2085 has been designed to maximize the performance of the LTC2000. The LTC2000 drives two 50Ω resistors on each side to minimize the impedance it sees. This maximizes the SFDR the DAC is able to produce. If a larger signal swing is required this impedance can be increased, but the SFDR might degrade. The output also has a pi network of 50Ω resistors to pad the output impedance of the board up to 50Ω per side. This allows the demo board to drive a 50Ω analyzer through a balun or other combiner.

Linear Technology has various coupon boards for specific frequencies and applications. More information is available at www.linear.com.

SAMPLE CLOCK

The sample clock to the DC2085 demonstration circuit board is marked J4. As a default it is a single-ended 50Ω input port. There is an onboard balun that does a single-ended to differential translation.

For the best noise performance, the sample input must be driven with a very low jitter signal generator source. The amplitude should be as large as possible up to ±1.8V or 9dBm.

SOFTWARE

The software for the DC2085, LTDACGen is available at www.linear.com free of charge. It simplifies the creation of complex waveforms and loading them into the FPGA to test the DC2085. For more information about how to use the LTDACGen software, refer to the help files that come with the software.

RESULTS

After everything is set up and the software is con-nected to the DAC demo system, a sine wave can be added to the output waveform. The default frequency is 399.932861328MHz (Figure 3). By clicking Update FPGA, the data is sent to the FPGA and is then used to program the DAC. A spectrum analyzer can then be used to view the results (Figure 4).
