The Renesas Electronics 5P49V6965 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 I2C interface. This is IDT’s sixth generation of programmable clock technology (VersaClock 6E).

Flexible 1.8V, 2.5V, 3.3V power-rails
High-performance, low phase noise PLL, < 0.5ps RMS typical
phase jitter on outputs
Four banks of internal OTP memory
In-system or factory programmable
2 select pins accessible with processor GPIOs or
bootstrapping
I2C serial programming interface
0xD0 or 0xD4 I2C address options allows multiple devices
configured in a same system
