DS90CR484VJD/NOPB datasheet by Texas Instruments

DS90CR484VJD/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the DS90CR484VJD/NOPB to ensure optimal performance?
  Texas Instruments provides a recommended PCB layout in the DS90CR484VJD/NOPB evaluation module (EVM) user's guide, which includes guidelines for trace routing, component placement, and power supply decoupling. Following this layout can help minimize signal integrity issues and ensure optimal performance.
• How do I configure the DS90CR484VJD/NOPB for a specific application, such as a camera interface or a display interface?
  The DS90CR484VJD/NOPB is a highly configurable device, and the configuration depends on the specific application. Texas Instruments provides a software development kit (SDK) that includes a graphical user interface (GUI) tool, which allows users to configure the device for their specific application. The SDK also includes example code and documentation to help with the configuration process.
• What is the maximum cable length supported by the DS90CR484VJD/NOPB, and how does it affect signal integrity?
  The maximum cable length supported by the DS90CR484VJD/NOPB depends on the specific application and the type of cable used. In general, the device supports cable lengths up to 10 meters at a data rate of 1.5 Gbps. However, signal integrity can be affected by the cable length, and users may need to use repeaters or active cables to extend the cable length. Texas Instruments provides guidelines for cable selection and signal integrity in the device's datasheet and application notes.
• How does the DS90CR484VJD/NOPB handle clock skew and jitter, and what are the recommended clocking schemes?
