Overview

The 8V79S674 is a clock divider and fanout buffer. The device has been designed for clock signal division in wireless base station radio equipment boards. The device is optimized to deliver excellent additive phase jitter performance. The 8V79S674 uses SiGe technology for an optimum of high clock frequency and low phase noise performance, combined with high power supply noise rejection. The device offers the frequency division by ÷1, ÷2, ÷4 and ÷8. Four low-skew LVPECL outputs are available and support clock output frequencies up to 2.5GHz (÷1 frequency division). Outputs can be disabled to save power consumption if not used. The device is packaged in a lead-free (RoHS 6) 20-lead VFQFN package. The extended temperature range supports wireless infrastructure, telecommunication and networking end equipment requirements.
