ADC08DJ3200 - 8-Bit, Dual 3.2-GSPS or Single 6.4-GSPS, RF-Sampling Analog-to-Digital Converter (ADC)

The ADC08DJ3200 device is an RF-sampling, giga-sample, analog-to-digitalconverter (ADC) that can directly sample input frequencies from DC to above 10 GHz. In dual-channelmode, the ADC08DJ3200 can sample up to 3200 MSPS and upto 6400MSPS in single-channel mode. Programmable tradeoffs in channel count (dual-channel mode) andNyquist bandwidth (single-channel mode) allow development of flexible hardware that meets the needsof both high channel count or wide instantaneous signal bandwidth applications. Full-power inputbandwidth (–3 dB) of 8.0 GHz, with usable frequencies exceeding the –3-dB point in both dual- andsingle-channel modes, allows direct RF sampling of L-band, S-band, C-band, and X-band for frequencyagile systems.

The ADC08DJ3200 uses a high-speed JESD204B output interface with up to 16serialized lanes and subclass-1 compliance for deterministic latency and multi-devicesynchronization. The serial output lanes support up to 12.8 Gbps and can be configured to trade-offbit rate and number of lanes. At 5 GSPS, only four total lanes are requiredrunning at 12.5 Gbps or 16 lanes can be used to reduce the lane rate to 3.125 Gbps.Innovative synchronization features, including noiseless aperture delay(T_AD) adjustment and SYSREF windowing, simplify system design for phasedarray radar and MIMO communications.
