SSDCI3138AF Spread Spectrum Clock Generator Ultra Low Power M obile EMI Reduction IC
■The SSDCI3138 AF is a versatile 1x spread spectrum frequency modulator designed to reduce electromagnetic interference (EMI) clock and data source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The SSDCI3138AF allows significant system cost savings reducing the number of circuit board laye,rs ferrite beads, shielding and other passive components that are traditionally required to pass EMI regulations.
■The SSDCI3138AF family of mobile active EMI management ICs are unique in their design by elimiating the use of conventional PLLs. This allows operation on aperiodic as well periodic signals. The peak energy is distributed over a wider and controlled energy band thereby significantly lowering system EMI compared to the typical narrow band signal produced by oscillators and most frequency generators. Lowering EMI by increasing a signal’s bandwidth is known as “Spread Spectrum” or active EMI management.
■3138 has an input frequency range of 10 MHZ to 60 MHz over a wide voltage range of 1.65V to 3.6V and generates a 1x spread spectrum coutput. The device can be placed in “power save mode” by setting the PDB pin to GND where in it draws typically 0.1uA and also stes the MODOUT pin to a High-Z state. The device has to “deviation control pins” SS1 and SS0 to allow flexibility and optimization of both EMI compliance as well in system design.
