12-Bit, 4.0 GSPS RF sampling ADC with JESD204B interface - ADC12J4000

ADC12J4000 (ACTIVE)

12-Bit, 4.0 GSPS RF sampling ADC with JESD204B interface

Description

The ADC12J4000 device is a wideband sampling and digital tuning device. Texas Instruments’ giga-sample analog-to-digital converter (ADC) technology enables a large block of frequency spectrum to be sampled directly at RF. An integrated DDC (Digital Down Converter) provides digital filtering and down-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 on the digital down-converter (DDC) decimation and link output rate settings, this data is output on 1 to 5 lanes of the serial interface.

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

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