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.
The LM15851 device
is available in a 68-pin
VQFN package. The device operates over the Industrial (–40°C ≤ TA ≤ 85°C)
ambient temperature range.
