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
2
C
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
2
C
addresses to allow multiple devices to be used in a system.
Features
Generates up to two independent output frequencies
High performance, low phase noise PLL, <0.7 ps RMS
typical phase jitter on outputs
Two fractional output dividers (FODs)
Independent Spread Spectrum capability on each output
Four banks of internal non-volatile in-system
programmable or factory programmable OTP memory
