5P49V5935

Programmable Clock Generator 5P49V5935 DATASHEET Description 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 I2C interface. This is IDTs fifth generation of programmable clock technology (VersaClock® 5). The 5P49V5935 by default uses an integrated 25MHz crystal as input reference. It also has a redundant external clock input. A glitchless manual switchover functions allows selection of either one as mentioned above as input reference during normal operation. Two select pins allow up to 4 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.
