Description
The 5P49V6965 is a member of the VersaClock® 6E programmable clock generator family. The 5P49V6965 is intended for high-performance consumer, networking, industrial, computing, and data-communications applications. The reference clock can come from one of the two redundant clock inputs. A glitchless manual switchover function allows one of the redundant clocks to be selected during normal operation.
Configurations may be stored in on-chip One-Time Programmable (OTP) memory or changed using I²C interface.

For 5P49V6965. What does the Perform margin read/user read do?
In the programming flow, after the step 12- Perform margin read, the device stops responding. After the STOP bit sent for the Step 12, a delay of 100ms is added. Then the device fails to ack after the slave address being sent. This behavior is also observed after the user ...

5P49V6965 Phase Shift Won't Exceed 110 degrees
Hello I am working with the 5P49V6965 on a custom devboard as well as the 5P49V6965-EVB. I am having trouble getting any of the outputs to have more than 110 degrees phase shift from each other.The Timing Commander software allows me to set higher values but after 110 ...
