SI5335B-B01909-GMR

The Skyworks Solutions SI5335B-B01909-GMR is a versatile clock generator and buffer IC capable of synthesizing four independent frequencies up to 350 MHz. Utilizing MultiSynth fractional divider technology, it guarantees 0 ppm frequency synthesis error. This device supports multiple configurations, allowing it to replace several clock ICs and crystal oscillators.

Key electrical specifications include output frequencies ranging from 1 MHz to 350 MHz for LVPECL/LVDS/CML and SSTL/HSTL, and up to 250 MHz for HCSL, and up to 200 MHz for CMOS. Input reference flexibility includes external crystal (25/27 MHz), CMOS (10-200 MHz), SSTL/HSTL (10-350 MHz), and differential (10-350 MHz). It offers independent output voltage control (1.5, 1.8, 2.5, or 3.3 V) and a single supply core voltage (1.8, 2.5, 3.3 V). The device features low phase jitter of 0.7 ps RMS and selectable PLL loop bandwidths of 1.6 MHz or 475 kHz.

Designed for ease of system integration, the SI5335B provides up to five user-assignable pin functions for spread spectrum control, reset, output enables, and frequency plan selection. It is compliant with PCIe Gen 1/2/3/4 common clock and Gen 3 SRNS standards. The device is available in a 24-VFQFN exposed pad package and is designed for surface mounting.
