Texas Instruments ADC12DL3200 RF-Sampling ADC

Texas Instruments ADC12DL3200 RF-Sampling Analog-to-Digital Converter (ADC) is an RF-sampling, giga-sample, analog-to-digital converter (ADC) that can directly sample input frequencies from DC to above 10GHz.  In the dual-channel mode, the ADC12DL3200 can sample up to 3200MSPS, and in single-channel mode, up to 6400MSPS. Programmable trade-offs in channel count (dual-channel mode) and Nyquist bandwidth (single-channel mode) allow the development of flexible hardware. This hardware meets the needs of both high-channel-count or wide instantaneous signal bandwidth applications. Full-power input bandwidth (–3dB) of 8.0GHz and a useable frequency range allow direct RF sampling of L-band, S-band, C-band, and X-band for frequency agile systems.
