83947AYI-147LF Description

Short technical summary and product information.

The Renesas 83947AYI-147LF is a clock fanout buffer and multiplexer integrated circuit. It features a 2-input to 9-output configuration, allowing distribution of two clock signals to nine separate outputs. The device operates at a maximum frequency of 250 MHz and supports LVCMOS and LVTTL logic levels on both inputs and outputs.

 

This IC is designed for surface-mount assembly in a 32-lead TQFP package (7x7 mm). It operates over a supply voltage range of 2.375V to 3.6V and an industrial temperature range of -40°C to +85°C. The device does not support differential signaling, making it suitable for single-ended clock distribution applications.

 

Typical applications include clock distribution in telecommunications, networking, data centers, servers, and industrial systems where precise timing and multiple clock signal routing are required. The low-skew and low-jitter characteristics ensure reliable high-speed clock distribution for digital logic circuits.
