DESCRIPTION

· The Si544 Ultra Series™ oscillator uses Skyworks Solutions’ 4th generation DSPLL® technology for ultra-low jitter and low phase noise clock generation.

· It is programmable via I2C commands to output frequencies from 0.2 to 1500 MHz with <1 ppb resolution.

· 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 in 1-2 weeks post-order.

· Factory-configurable for various user specifications, reducing lead times for custom oscillators.

FEATURES

· I2C programmable with frequencies from 0.2 to 1500 MHz at <1 ppb resolution.

· Ultra-low jitter: 150 fs Typ RMS (12 kHz – 20 MHz).

· Supports up to 4 pin-selectable startup frequencies.

· I2C interface supports 100 kbps, 400 kbps, and 1 Mbps (Fast Mode Plus).

· Excellent PSNR and supply noise immunity: –80 dBc Typ.

· Operates at 3.3 V, 2.5 V, and 1.8 V VDD from the same part number.

· Multiple output options: LVPECL, LVDS, CML, HCSL, CMOS, and Dual CMOS.

· Available in 2.5x3.2, 3.2x5, 5x7 mm package options.

APPLICATIONS

· Suitable for 100G/200G/400G OTN, coherent optics, PAM4.

· Ideal for 10G/40G/100G optical ethernet.

· Used in 3G-SDI/12G-SDI/24G-SDI broadcast video.

· Applicable in servers, switches, storage, and search acceleration.

· Useful in test and measurement environments.

· Effective for FPGA/ASIC clocking.
