Texas Instruments provides a recommended layout and routing guide in the ADS6244IRGZR Evaluation Module User's Guide (SLAU445). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
The ADS6244IRGZR datasheet provides a general guideline for the analog input filter. However, the optimal filter design depends on the specific application's frequency range, noise environment, and signal amplitude. Engineers can use tools like the TI FilterPro software or consult with TI's application engineers for customized filter design support.
While the datasheet specifies a maximum clock frequency of 65 MSPS, the actual maximum clock frequency may vary depending on the system's noise environment, PCB layout, and signal integrity. It's recommended to consult with TI's application engineers or perform thorough system-level testing to determine the optimal clock frequency for a specific design.
The ADS6244IRGZR outputs 14-bit digital data in a binary two's complement format. Engineers should ensure that their digital signal processing (DSP) or microcontroller (MCU) can handle this data format and perform any necessary data manipulation, such as offset correction, gain adjustment, or data formatting for further processing or transmission.
The POR timing is not explicitly specified in the datasheet. However, according to TI's application engineers, the POR timing is typically around 10 ms to 20 ms. Engineers should ensure that their system design allows for sufficient power-on reset time to ensure proper device initialization and operation.
