Overview

Description

The IDT 5P49V5923 is low-power programmable clock generator with best-in-class jitter performance and design flexibility with LVCMOS outputs capable of generating any output frequency. The 5P49V5923 is 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 IDT’s fifth generation of programmable clock technology (VersaClock 5). The frequencies are generated from a single reference clock or crystal input. A glitchless manual switchover function allows one of the redundant clock inputs 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.
