Programmable Fanout Buffer 5P1103
Description
The 5P1103 is a programmable fanout buffer 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.
The outputs are generated from a single reference clock. The
input reference can be crystal, external single-ended or
differential clock. The reference clock can come from one of
the two redundant clock inputs and is selected by CLKSEL
pin. A glitchless manual switchover function allows one of the
redundant clocks to be selected during normal operation. See
reference clock input section for details.
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.
