Programmable Clock Generator
5P49V6901
DATASHEET
Description
The 5P49V6901 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® 6).
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.
