5P49V5908
Programmable Clock Generator
5P49V5908
Description
The 5P49V5908 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 frequencies are generated from a single reference clock
or crystal. 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.
The device may be configured to use one of two I2C
addresses to allow multiple devices to be used in a system.
