描述 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 I2C

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 I2C

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