DESCRIPTION

· The Si549 Ultra Series™ oscillator employs Skyworks Solutions’ 4th generation DSPLL® technology for ultra-low jitter and phase noise clocks.
· Programmable via I2C commands, it offers frequencies from 0.2 to 1500 MHz with less than 1 ppb resolution.
· Features on-chip power supply filtering for superior noise rejection in systems with switched-mode power supplies.
· Simplifies supply chain with custom frequency samples available 1-2 weeks post-order.
· Factory-configurable for various user specifications, eliminating long lead times for custom oscillators.

FEATURES

· I2C programmable with ultra-low jitter of 95 fs RMS.
· Supports up to 4 pin-selectable startup frequencies.
· I2C interface supports speeds up to 1 Mbps.
· Excellent power supply noise rejection at -80 dBc.
· Operates at 3.3 V, 2.5 V, and 1.8 V supply voltages.
· Offers multiple output formats including LVPECL, LVDS, and CMOS.
· Available in 2.5x3.2, 3.2x5, 5x7 mm package options.
