Description
The ADC12DJ3200QML-SP device is an RF-sampling, giga-sample, analog-to-digital converter (ADC) that can directly sample input frequencies from dc to above 10 GHz. In dual-channel mode, the ADC12DJ3200QML-SP can sample up to 3200 MSPS. In single-channel mode, the device can sample up to 6400 MSPS. Programmable tradeoffs in channel count (dual-channel mode) and Nyquist bandwidth (single-channel mode) allow development of flexible hardware that meets the needs of both high channel count or wide instantaneous signal bandwidth applications. Full-power input bandwidth (–3 dB) of 7 GHz, with usable frequencies exceeding the –3-dB point in both dual- and single-channel modes, allows direct RF sampling of L-band, S-band, C-band, and X-band for frequency agile systems.
The ADC12DJ3200QML-SP uses a high-speed JESD204B output interface with up to 16 serialized lanes and subclass-1 compliance for deterministic latency and multidevice synchronization. The serial output lanes support up to 12.8 Gbps, and can be configured to trade off bit rate and number of lanes. Innovative synchronization features, including noiseless aperture delay (tAD) adjustment and SYSREF windowing, simplify system design for synthetic aperture radar (SAR) and phased-array MIMO communications. Optional digital down converters (DDCs) in dual-channel mode allow for reduction in interface rate (real and complex decimation modes) and digital mixing of the signal (complex decimation modes only).
