Texas Instruments  ADC12J4000NKET

The ADC12J4000 deviceis a wideband sampling anddigital tuning device. Texas Instruments’ giga-sampleanalog-to-digital converter (ADC) technology enables a large block of frequency spectrum to besampled directly at RF. An integrated DDC (Digital Down Converter) provides digital filtering anddown-conversion. The selected frequency block is made available on a JESD204B serial interface.Data is output as baseband 15-bit complex information for ease of downstream processing. Based onthe digital down-converter (DDC) decimation and link output rate settings, this data is output on 1to 5 lanes of the serial interface.

A DDC bypass mode allows the full rate 12-bit raw ADC data toalso be output. This mode of operation requires 8 lanes of serial output.

The ADC12J4000 deviceis available in a 68-pinVQFN package. The device operates over the Industrial (–40°C ≤ TA ≤ 85°C)ambient temperature range.
