Description
The 5P49V6965 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 I2
C interface. This is Renesas’ sixth generation of
programmable clock technology (VersaClock 6E).
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 four 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 I2
C addresses to allow multiple devices to be used in a
system
