5P49V5901 Datasheet PDF – Programmable Clock Generator
Power Programmable Clock Generator
5P49V5901 overview
The 5P49V5901 is a Power Programmable Clock Generator, supplied in a 24-pin VFQFPN package. The absolute maximum ratings table on this page lists the 21 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the 5P49V5901 pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The 5P49V5901 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
The frequencies are generated from a single reference clock. The reference clock can come from one of the two redundant clock inputs. A glitchless manual switchover function allows one of the redundant clocks to be selected 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. The device may be configured to use one of two I2C addresses to allow multiple devices to be used in a system
