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. Two select pins allow up to 4 different configurations to be programmed and accessible using processor GPIOs or bootstrapping. The device is available in 24-pin VFQFPN 4mm x 4mm package, with an industrial operating temperature range of -40° to +85°C.
