The Skyworks Solutions SI5344B-D10483-GMR is a versatile clock multiplier and jitter attenuator designed for high-performance timing applications. It utilizes advanced DSPLL™ and MultiSynth™ technologies to generate any output frequency from any input frequency, with ultra-low jitter of 90 fs rms.
This device supports a wide range of input frequencies from 8 kHz to 750 MHz (differential) and 8 kHz to 250 MHz (LVCMOS). Output frequencies can range from 100 Hz to 1028 MHz (differential) and 100 Hz to 250 MHz (LVCMOS). The jitter attenuation bandwidth is digitally programmable from 0.1 Hz to 4 kHz, allowing for application-specific optimization. The outputs are highly configurable and compatible with LVDS, LVPECL, LVCMOS, CML, and HCSL standards.
Programmable via a serial interface with in-circuit programmable non-volatile memory (NVM), the SI5344B-D10483-GMR ensures a known frequency configuration upon power-up. It supports free-run, synchronous, and holdover modes, along with automatic and manual input clock switching. The integrated loop filter eliminates noise coupling issues common with discrete solutions.
Applications include OTN muxponders and transponders, 10/40/100 G networking line cards, GbE/10 GbE/100 GbE Synchronous Ethernet (ITU-T G.8262), carrier Ethernet switches, SONET/SDH line cards, broadcast video, and test and measurement equipment. The device is available in a 44-QFN package and is suitable for surface mount applications.
