Description
The 5P49V6901 is a programmable clock generator intended for high-performance consumer, networking, industrial, computing, and data communications applications. Configurations may be stored in on-chip One-Time Programmable (OTP) memory or changed using the I2C interface. This is Renesas' sixth generation of programmable clock technology (VersaClock® 6). The frequencies are generated from a single reference clock. 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.
Two select pins allow up to four different configurations to be programmed and accessible using processor GPIOs or bootstrapping. The different selections may be used for different operating modes (full function, partial function, partial power down), regional standards (US, Japan, Europe), or system production margin testing. The device may be configured to use one of two I2C addresses to allow multiple devices to be used in a system.

- Multi-function printers
- Processor and FPGA clocking
- Any-frequency clock conversion
- MSAN/DSLAM/PON
- Fiber Channel, SAN
- Telecom line cards
- 1GbE and 10GbE

5P49V6965 vs 5P49V6901
I have a 5P49V6965 in a design that previously used a 5P49V6901. The same configuration used for the 5P49V6901, doesn't appear to be operationally compatible with the 5P49V6965. With the 5P49V6901, I've been able to: Have outputs 3/4 on always on Have exclusive output control of ...

Personality File for 5P49V6965A000NLGI
Hello, we have updated a new clock generator (5P49V6965A000NLGI) on a new board design and need a personality file to edit clocks. Where can I find this? For reference I have a register settings dump of the old generator that works for us. OLD (5P49V6901A000NLGI) i2cdump -y 0 0x6a c ...
