  • ADS54J66: Termination requirement for SYNCbAB & SYNCbCD

    TI Thinks Resolved
    Part Number: ADS54J66 Hi Let me Know the termination required for SYNbAB & SYNbCD pins. Datasheet recommends to provide termination and also in Figure 144. Application Diagram for the ADS54J66, it is mentioned to provide 1.2V. Kindly provide the value…

  • ADS54J66: ADC input Voltage Range

    TI Thinks Resolved
    Part Number: ADS54J66 Hi I am using ADS54J66 in my application. Common Mode voltage = 2v peak to Peak = 1.9v So at the ADC input, if we probe we will get voltage from 2 - (pk_to_pk / 2) to 2 + (pk_to_pk / 2) ie.. from 1.05 to 2.95 . Right ?? Also …

  • ADS54J66: dBFS to dB Convertion

    Part Number: ADS54J66 Hi In the ADS54J66 datasheet, I found these Specifications All the Spectifications are in dBFS I am confused of this conversion. Can you guide me with the conversion from dBFS to dB ?

  • ADS54J66: Is there any registers for SYSREF± and lets the user know if the SYSREF± signal is captured by the ADC?

    Part Number: ADS54J66 Hi Sir, In our project, we want to achieve power-up deterministic phase by JESD204B. However, till now, the power-up phase is not deterministic. We'd like to check the status of SYSREF± to know if the SYSREF± signal is captured…
