3 Description

ADC12QJ1600-SP is a quad channel, 12-bit, 1.6GSPS analog-to-digital converters (ADC). Low power consumption, high sampling rate and 12-bit resolution makes the device suited for a variety of multi-channel communications systems.

Full-power input bandwidth (-3dB) of 6GHz enables direct RF sampling of L-band and S-band.

A number of clocking features are included to relax system hardware requirements, such as an internal phase-locked loop (PLL) with integrated voltage controlled oscillator (VCO) to generate the sampling clock. Four clock outputs are provided to clock the logic and SerDes of the FPGA or ASIC. A timestamp input and output is provided for pulsed systems.

JESD204C serialized interface decreases system size by reducing the amount of printed circuit board (PCB) routing. Interface modes support from 2 to 8 lanes (dual and quad channel devices) or 1 to 4 lanes (for the single channel device), with SerDes baud-rates up to 17.16Gbps, to allow the optimal configuration for each application.
