TSW12QJ1600 ADC Evaluation Module (EVM)

Texas Instruments TSW12QJ1600EVM ADC Evaluation Module (EVM) is used to evaluate the ADC12QJ1600-Q1 analog-to-digital converter (ADC) with different front-end options. ADC12QJ1600-Q1 is a 12-bit ADC capable of operating at sampling rates up to 1.6 Giga samples per second (GSPS) with four analog input channels. This evaluation module has two ADC12QJ1600-Q1 devices on the same printed circuit board (PCB). These can be used to demonstrate multiple ADC synchronizations, deterministic latency, and test the performance of the ADC with various front-end options (AC-coupled transformer; DC-coupled option with LMH32401). The design also demonstrates how the clocking scheme can be simplified by daisy-chaining the PLL reference output (PLLREFO+, PLLREFO-) from one ADC to another, eliminating the need for the clock-distribution chip that is usually needed by JESD devices.
