5P49V5935B000LTGI

The 5P49V5935 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 an I²C interface. This is Renesas' fifth generation of programmable clock technology (VersaClock^® 5). The 5P49V5935, by default, uses an integrated 25MHz crystal as an input reference. It also has a redundant external clock input. A glitchless manual switchover function allows the selection of either input reference 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.
