Programmable PLL Clock Generator Single 1MHz to 350MHz 24-Pin VFQFPN EP T/R

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). 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 device may be configured to use one of two I2C addresses to allow multiple devices to be used in a system.
