Programmable Clock Generator

5P49V5923

DATASHEET

Description

The 5P49V5923 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 I

interface. This is IDT’s fifth generation of programmable clock

technology (VersaClock

5).

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 I

addresses to allow multiple devices to be used in a system.
