SI5345A-D06383-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345A-D06383-GMR is a 10-channel jitter attenuator and clock multiplier from Skyworks Solutions. It supports any-frequency generation with differential outputs ranging from 100 Hz to 1028 MHz and LVCMOS outputs up to 250 MHz. The device features ultra-low jitter of 90 fs rms, four inputs (differential: 8 kHz–750 MHz; LVCMOS: 8 kHz–250 MHz), and operates on VDD at 1.8 V ±5% and VDDA at 3.3 V ±5%. It utilizes a 64-QFN 9×9 mm package and functions within a temperature range of –40 to +85 °C.
