2 Matched ADCs with Input Signal Conditioning

Selectable Bipolar Input Voltage Range (/H115500.5 V, /H115501.0 V, /H115502.0 V) Full MIL-STD-883B Compliant 80 dB Spurious-Free Dynamic Range Trimmed Channel-Channel Matching

APPLICATIONS

Any I/Q Signal Processing Application The AD10242 operates with ± 5.0 V for the analog signal condi- tioning with a separate 5.0 V supply for the analog-to-digital conversion. Each channel is completely independent, allowing operation with independent encode or analog inputs. The AD10242 also offers the user a choice of analog input signal ranges to mini- mize additional signal conditioning required for multiple functions within a single system. The heart of the AD10242 is the AD9042, which is designed s pecifically for applications requiring wide dynamic range. The AD10242 is manufactured on Analog Devices’ MIL-PRF-38534 MCM line and is completely qualified. Units are packaged in a custom, cofired, ceramic 68-lead gull wing package and specified for operation from –55 °C to +125 °C. Contact the factory for additional custom options including those that allow the user to ac couple the ADC directly, bypassing the front end amplifier section. Also see the AD9042 data sheet for additional details on ADC performance. PRODUCT HIGHLIGHTS 1. Guaranteed sample rate of 40 MSPS. 2. Dynamic performance specified over entire Nyquist band; spurious signals @ 80 dBc for –1 dBFS input signals. 3. Low power dissipation: <2 W off ±5.0 V supplies. 4. User defined input amplitude. 5. Packaged in 68-lead ceramic leaded chip carrier. GENERAL DESCRIPTION The AD10242 is a complete dual signal chain solution including on-board amplifiers, references, ADCs, and output buffering providing unsurpassed total system performance. Each channel is laser trimmed for gain and offset matching and provides channel- to-channel crosstalk performance better than 80 dB. The AD10242 utilizes two each of the AD9632, OP279, and AD9042 in a cus- tom MCM to gain space, performance, and cost advantages over solutions previously available.

–6– Overvoltage Recovery Time The amount of time required for the converter to recover to 0.02% accuracy after an analog input signal of the specified percentage of full scale is reduced to midscale. Power Supply Rejection Ratio The ratio of a change in input offset voltage to a change in power supply voltage. Signal-to-Noise and Distortion (SINAD) The ratio of the rms signal amplitude (set at 1 dB below full scale) to the rms value of the sum of all other spectral compo- nents, including harmonics but excluding dc. Signal-to-Noise Ratio (SNR, without Harmonics) The ratio of the rms signal amplitude (set at 1 dB below full scale) to the rms value of the sum of all other spectral compo- nents, excluding the first five harmonics and dc. Spurious-Free Dynamic Range (SFDR) The ratio of the rms signal amplitude to the rms value of the peak spurious spectral component. The peak spurious compo- nent may or may not be a harmonic. SFDR may be reported in dBc (i.e., degrades as signal levels are lowered) or in dBFS (always r elated back to converter full scale). Transient Response The time required for the converter to achieve 0.02% accu- racy when a one-half full-scale step function is applied to the analog input. Two-Tone Intermodulation Distortion Rejection The ratio of the rms value of either input tone to the rms value of the worst third order intermodulation product; reported in dBc. Two-Tone SFDR The ratio of the rms value of either input tone to the rms value of the peak spurious component. The peak spurious component may or may not be an IMD product. Two-tone SFDR may be reported in dBc (i.e., degrades as signal levels are lowered) or in dBFS (always related back to converter full scale). DEFINITION OF SPECIFICATIONS Analog Bandwidth The analog input frequency at which the spectral power of the fundamental frequency (as determined by the FFT analysis) is reduced by 3 dB. Aperture Delay The delay between the 50% point of the rising edge of the ENCODE command and the instant at which the analog input is sampled. Aperture Uncertainty (Jitter) The sample-to-sample variation in aperture delay. Differential Nonlinearity The deviation of any code from an ideal 1 LSB step. Encode Pulsewidth/Duty Cycle Pulsewidth high is the minimum amount of time that the ENCODE pulse should be left in Logic “1” state to achieve rated performance; pulsewidth low is the minimum time that the ENCODE pulse should be left in low state. At a given clock rate, these specifications define an acceptable encode duty cycle. Harmonic Distortion The ratio of the rms signal amplitude to the rms value of the worst harmonic component. Integral Nonlinearity The deviation of the transfer function from a reference line measured in fractions of 1 LSB using a “best straight line” deter- mined by a least square curve fit. Minimum Conversion Rate The encode rate at which the SNR of the lowest analog signal frequency drops by no more than 3 dB below the guaranteed limit. Maximum Conversion Rate The encode rate at which parametric testing is performed. Output Propagation Delay The delay between the 50% point of the rising edge of the ENCODE command and the time when all output data bits are within valid logic levels. REV. D
