Silicon Labs EMI Reduction Clock Si5351A-A-GU

Silicon Labs' programmable spread spectrum clock generators feature a wide range of programming options that allow system designers to minimize electro-magnetic interference (EMI) at the application level.

Configurable parameters to reduce EMI include a wide range of signal integrity adjustments like rise/fall times, output impedance, drive strength, programmable edge rates, programmable skew and spread spectrum percentage/modulation rate.

Features:

• Any frequency, any-bank frequencies from 1 MHz to 200 MHz
• Single input with 8 CMOS outputs organized into 4 banks
• Independent VDDO per output eliminates external level translators (1.8, 2.5, 3.3V)
• Low period jitter: 50 ps pk-pk
• Crystal (25 or 27 MHz) or clock (5-200MHz) input
• I²C programmable (Si5356) supports spread spectrum
• Si5356 in-system, flash-based programmable with small form factor MCU

Silicon Labs' highly flexible, factory and I²C programmable and factory customizable LVCMOS clock generators can be customized to generate multiple independent non-integer-related frequencies with equivalent frequency synthesis capability of 8 PLLs, with exact frequency synthesis (0 ppm error), at significantly lower jitter, lower power and smaller size than competing solutions. Factory customized options are available to minimize EMI, including programmable edge rates, programmable impedance and programmable skew.
