3 Description

ADC12QJ1600-SEP is a quad channel, 12-bit, 1.6

GSPS analog-to-digital converters (ADC). Low power

consumption, high sampling rate and 12-bit resolution

makes the device suited for a variety of mulch-chanel

communications systems.

Full-power input bandwidth (-3 dB) of 6 GHz 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 voltagecontrolled

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 17.16 Gbps, to allow the optimal configuration for

each application.
