Silicon Labs EMI Reduction Clock Si5356

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' PCI Express clocks provide industry-leading jitter performance, compliance with PCI Express (PCIe) Gen 1/2/3 requirements, outstanding frequency flexibility and configurable AC parameters for signal integrity optimization.

The PCIe Clock family addresses the specific clock requirements of PCIe Generation 1, 2, or 3 system interfaces. This interface standard has become the industry choice as a high speed interconnect between devices and system I/Os and is used in consumer, server, storage, IP gateways, multi-function printers (MFPs) and industrial applications.

Features:

• Lowest jitter PCIe Gen 3 clock
• Any frequency or any output (< 350 MHz)
• Integrated level/format translation (HCSL, LVDS, LVCMOS, LVPECL)
• Pin/I²C programmable
• Custom solutions available (contact Silicon Labs)
