Summary
The Texas Instruments ADC12QJ1600-SP is a quad-channel, 12-bit, 1.6 GSPS analog-to-digital converter (ADC).
It has a low power consumption, high sampling rate, and 12-bit resolution, making it well-suited for a variety of multi-channel communications systems.
A number of clocking features are included to relax system hardware requirements, such as an internal phase-locked loop (PLL) with an 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 are provided for pulsed systems.
Applications
- Electronic warfare (SIGINT, ELINT)
- Satellite communications (SATCOM)
Key features
- ADC Core:
- Resolution: 12 Bit
- Maximum sampling rate: 1.6 GSPS
- Non-interleaved architecture
