Overview
Description
The 874328I-01 is a high-performance differential ÷1 and ÷4 clock divider and fanout buffer. The device is designed for the frequency-division and signal fanout of high-frequency, low phase-noise clock signals. The differential input signal is frequency divided by ÷1 and ÷4. Three LVPECL and three LVDS output banks are provided with a total of twenty differential outputs. The 874328I-01 is characterized to operate from a 2.5V power supply. Guaranteed output-to-output and part-to-part skew characteristics make the 874328I-01 ideal for those clock distribution applications demanding well-defined performance and repeatability.
