Texas Instruments LM15851 12-Bit, Ultra-wideband RF sampling subsystem LM15851NKET

The LM15851NKET is a 12-bit ultra-wideband RF sampling subsystem designed by Texas Instruments. It features a maximum sampling rate of 4000 MSPS and a minimum sampling rate of 1000 MSPS, making it suitable for high-speed applications. The device includes a configurable digital down converter (DDC) with decimation factors ranging from 4 to 32, allowing for flexible output bandwidths of 800 MHz at 4x decimation and 100 MHz at 32x decimation. The output data is provided as 15-bit complex information via a low pin-count JESD204B interface, which automatically optimizes the output lane count based on the selected settings. The LM15851NKET operates within an industrial temperature range of -40¬8C to 85¬8C and is housed in a 68-pin VQFN package. It is characterized by low power consumption, with only 2 W during operation at 4000 MSPS with decimation by 10, and less than 50 mW in power-down mode. The device is suitable for applications in wireless infrastructure, software-defined radio, wideband microwave backhaul, and DOCSIS/cable infrastructure.
