DESCRIPTION

· The Si564 Ultra Series™ oscillator employs Skyworks Solutions’ 4th generation DSPLL® technology for ultra-low jitter and phase noise across 0.2 to 3000 MHz.
· It is programmable via I2C with <1 ppb resolution, ensuring precise frequency control.
· Features on-chip power supply filtering for superior noise rejection, ideal for systems with switched-mode power supplies.
· Simplifies supply chain with custom frequency samples available 1-2 weeks post-order.
· Factory-configurable for startup frequency, I2C address, output format, and OE pin settings, reducing lead times.

FEATURES

· I2C programmable frequency range from 0.2 to 3000 MHz with <1 ppb resolution.
· Ultra-low jitter: 90 fs RMS typical (12 kHz – 20 MHz).
· Supports up to 4 pin-selectable startup frequencies.
· I2C interface compatible with 100 kbps, 400 kbps, and 1 Mbps (Fast Mode Plus).
· Exceptional PSNR and supply noise immunity: -80 dBc typical.
· Operates at 3.3 V, 2.5 V, and 1.8 V VDD from the same part number.
· Offers multiple output options: LVPECL, LVDS, CML, HCSL, CMOS, and Dual CMOS.
· Available in 2.5x3.2, 3.2x5, and 5x7 mm package options.

APPLICATIONS
