The recommended layout and routing for the ADS6443IRGCT involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the analog input traces. It's also important to keep the clock and digital signals away from the analog inputs.
To optimize the performance of the ADS6443IRGCT, ensure that the analog input signals are properly terminated, use a low-noise power supply, and minimize the noise on the reference voltage. Additionally, optimize the clock frequency and phase to minimize jitter and ensure proper synchronization.
The maximum input voltage range for the ADS6443IRGCT is ±VREF, where VREF is the reference voltage. The absolute maximum rating is 5.5V, but the recommended operating range is ±3.5V to ensure optimal performance.
The clock input for the ADS6443IRGCT should be a low-jitter, high-frequency clock signal (typically 10-100 MHz). The clock signal should be properly terminated and should not exceed the maximum clock frequency rating of 100 MHz.
The latency of the ADS6443IRGCT is approximately 10 clock cycles, which corresponds to a latency of around 100 ns at a clock frequency of 100 MHz.
