DEMO MANUAL DC996 LTC2208/LTC2208-14/LTC2217/ LTC2216/LTC2215 16-Bit/14-Bit 80Msps to130Msps ADCs DESCRIPTION Demonstration circuit 996 supports a family of 16-/14-bit 80Msps to 130Msps ADCs. Each assembly features one of the following devices: LTC®2208, LTC2208-14, LTC2217, LTC2216, LTC2215 high speed, high dynamic range ADCs. This demonstration circuit only supports LVDS operation. For demonstration of CMOS output signaling, please see DC854. Other members of this family include the LTC2207, a 105Msps 16-bit CMOS-only version of this device, as well as lower speed versions and single-ended clock versions. These 7mm × 7mm QFN devices are supported by Demonstration Circuits 918 and 919 (for single-ended clock input). Several versions of the 996 demo board supporting the LTC2208 16-bit, LTC2217 16-bit and LTC2208-14 14-bit series of A/D converters are listed in Table 1. Depending on the required resolution, sample rate and input frequency, the DC996 is supplied with the appropriate ADC and with an optimized input circuit. The circuitry on the analog inputs is optimized for analog input frequencies below 70MHz or from 70MHz to 140MHz. For higher input frequencies, contact the factory for support.

Refer to Figure 1 for proper measurement equipment setup and follow this procedure: Setup If a DC890 QuikEval™ II Data Acquisition and Collection System was supplied with the DC996 demonstration circuit, follow the DC890 Quick Start Guide to install the required software and for connecting the DC890 to the DC996 and to a PC. DC996 Demonstration Circuit Board Jumpers The DC996 demonstration circuit board should have the following jumper settings as default: (as per Figure 1). Figure 1 shows DC996A, the DC996B is shown in Figure 7. J2: Mode (VCC) 2's Complement CDS Off J3: SHDN: (Run) Dither (Off) Applying Power and Signals to the DC996 Demonstration Circuit Apply 3.3V across the pins marked “+3.3V” and “PWR GND” on the DC996. The DC996 demonstration circuit requires up to 700mA depending on the sampling rate and the A/D converter supplied. If a DC890 is used to acquire data from the DC996, the DC890 must be provided with an external 6V ±0.5V 1A supply on turrets G7(+) and G1(–) or the adjacent 2.1mm power jack to support the power requirements of the Xilinx Spartan 3 FPGA active terminations used to terminate the LVDS repeaters on the DC996. The DC890 will not activate the LVDS mode unless the DC890 detects external power present. If external power is not present the DC890 will not configure the FPGA for LVDS terminations as this would result in exceeding the USB 500mA limit. The DC890 contains an onboard electronic circuit breaker which will shut off the DC890 if external power is removed while the FPGA is configured for LVDS active terminations.

See Figure 7 for DC996B Encode Clock Note: This is not a logic-compatible input. It is terminated with 50Ω. Apply an encode clock to the SMA connector on the DC996 demonstration circuit board marked “J7 ENCODE INPUT”. This is a transformer-coupled input, terminated on the secondary side in two steps, 100Ω at the transformer with final termination at the ADC at 100Ω. noise performance by reducing the wideband noise power of the signals. 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 broad band noise. Low phase noise Agilent 8644B generators are used with TTE bandpass filters for both the clock input and the analog input. For the best noise performance, the ENCODE INPUT must be driven with a very low jitter source. When using a sinusoidal generator, the amplitude should often be as large as possible, up to 3VP-P or 13dBm. Using bandpass filters on the clock and the analog input will improve the Apply the analog input signal of interest to the SMA connectors on the DC996 demonstration circuit board marked “J5 ANALOG INPUT”. These inputs are capacitive coupled to Balun transformers ETC1-1-13, or directly coupled through flux-coupled transformers ETC1-1T. dc996f 3 DEMO MANUAL DC996 QUICK START PROCEDURE An internally generated conversion clock output is available on J1 which could be collected via a logic analyzer, or other data collection system if populated with a SAMTEC MEC8-150 type connector or collected by the DC890 Data Acquisition Board using the PScope™ System Software provided or downloaded from the Linear Technology website at http://www.linear.com/designtools/software/. If a DC890 was provided, follow the DC890 Quick Start Guide and the instructions below. 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. Analog Input Network For optimal distortion and noise performance the RC network on the analog inputs should be optimized for the analog input frequencies of interest. At this point in time, the circuit in Figure 3 for input frequencies below 70MHz. For input frequencies from 70MHz to 140MHz, the circuit in Figure 2 is used. These two input networks cover a broad bandwidth and are not optimized for operation at a specific input frequency. For higher frequencies, a single balun (ETC1-1-13) is populated on a DC996A board. In almost all cases, filters will be required on both analog input and encode clock to provide data sheet SNR. If the DC996 demonstration circuit is properly connected to the DC890, PScope should automatically detect the DC996, and configure itself accordingly. If necessary the procedure below explains how to manually configure PScope. 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. Under the Configure menu, go to ADC Configuration. Check the Config Manually box and use the following configuration options: The DC996A board has provision for a bandpass filter prior to the balun. This may be populated if the board is customized for a given frequency band. (Figure 5) • 16-Bit (or 14-Bit if using LTC2208-14) In some cases, 3dB to 10dB pads may be required to obtain low distortion. • Alignment: Left-16 • Bipolar (2’s complement) • Positive clock edge • Type: LVDS 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. Additional information and help for PScope is available in the DC890 Quick Start Guide and in the online help available within the PScope program itself. 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 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. For advice on drive circuits or for input frequencies greater than 220MHz, or for higher order bandpass filtering prior to the ADC, contact the factory for support. dc996f 4 DEMO MANUAL DC996 QUICK START PROCEDURE 49.9Ω 0.1μF T1 MA/COM ETC1-1-13 ANALOG INPUT 33Ω 0.1μF T1 1:1 RESISTORS, CAPACITORS ARE 0402 PACKAGE SIZE EXCEPT 2.2μF 33Ω VCM 2.2μF 10Ω 5Ω AIN+ LTC2208 0.1μF 10Ω This board is used only for 200MHz+ applications.

If the higher frequency board is ordered without requesting a bandpass filter, C6 is a counterpart to C7, providing a DC block, C23 is a 0Ω resistor. Figure 2.

Analog Front-End Circuit For 1MHz < AIN < 70MHz For input frequencies less than 5MHz, or greater than 150MHz, other input networks may be more appropriate. Please consult the factory for suggestions on drivers and networks if your signal sources extend outside these ranges, or if you experience difficulties driving these suggested networks. If this is populated as a BP filter, The reactance of L1 and L3, and the series of C6 and C5 (and C21 and C23) should be between 50Ω and 33Ω. The reactance of L2 should match that of 1/2 C6^+C5. The ratio of C5 to C6 will determine coupling be-tween the two resonators, with a high ratio giving a narrow pass band. As an example, for center frequency of 260MHz; –3dB BW of 150MHz, C6, C23 = 27pF; C5, C21 = 68pF; L1, L3 = 18 nH; L2 = 7.5nH. This has a flat passband over 80MHz. See Figure 6. This filter is not intended as a band-defining filter, but simply to minimize noise BW prior to the ADC, and to minimize 2nd and 3rd originating in a drive amplifier. 2nd harmonic of 260 is down at 1. dc996f 5 DEMO MANUAL DC996 QUICK START PROCEDURE Figure 4.
