SI5345A-B04583-GMR

The Skyworks Solutions SI5345A-B04583-GMR is a versatile clock multiplier and jitter attenuator designed for high-performance timing applications. Leveraging advanced DSPLL™ and MultiSynth™ technologies, this device generates any output frequency from any input frequency with ultra-low jitter of 90 fs rms.

Key electrical specifications include input frequency ranges from 8 kHz to 750 MHz (Differential) and 8 kHz to 250 MHz (LVCMOS), with output frequencies up to 1028 MHz (Differential) and 250 MHz (LVCMOS). The jitter attenuation bandwidth is digitally programmable from 0.1 Hz to 4 kHz, allowing for application-specific optimization. It supports multiple output types including LVDS, LVPECL, LVCMOS, CML, and HCSL.

This device is housed in a 64-QFN 9x9 mm package and is suitable for surface mount applications. It features 4 input clocks and up to 10 output clocks, making it ideal for complex clock generation and distribution needs in networking, broadcast, and test and measurement equipment.

Programmable via a serial interface with in-circuit programmable non-volatile memory (NVM), the SI5345A-B04583-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.
