Femtocell Market Is BoomingThe Femtocell market is forecast to grow to $3.7B by 20201 at a CAGR of >40% Mobile data traffic is expected to grow 10x from 2013 to 20202
Expanding mobile network coverage by adding new towers would be prohibitively expensive
Femtocells give network operators a cost-effective way to expand coverage using the existing infrastructure
Femtocells must add components to provide the enhanced features the market requiresSeparate processors to support the WCDMA3 and LTE4 standards
On-board flash memory to store digital media content
A USB port to debug and program configuration settings
These additional components drive the need for multiple custom clock frequencies in the Femtocell
Cypress’s programmable clock generates the custom frequencies needed for your Femtocell system
Market Vision: To define the market opportunity. Presents compelling data and end product photos relevant to the local market. 3

FemtocellA small, low-power cellular base station connected to a mobile network via wired Internet, used in areas of poor cellular reception
Electromagnetic Interference (EMI)A disturbance that affects an electrical circuit, usually caused by electromagnetic radiation emitted by an external sourceOne primary source of electromagnetic radiation is clocks, because of their high frequency and periodic nature
Spread Spectrum ModulationA method used of reducing EMI by varying the frequency of a clock signal to spread its energy across a wider frequency range

Multiple clocks used in Femtocells increase cost and board spaceUp to six reference clock outputs may be required for the processors and peripherals
Programmable Clock for Femtocell (Six Outputs)
Fixed-frequency clocks can produce EMI that exceeds regulatory emission standardsTraditional EMI-reduction solutions, such as ferrite beads and chokes, increase cost and board space
EMI problems often require rework at the end of the development cycle, threatening time-to-market
Cypress’s programmable clock solves these problemsGenerates up to six custom frequencies in minutes
Saves cost and board space by eliminating multiple crystals, ferrite beads and chokes
Uses SS Modulation for quick and effective EMI reduction
Cypress’s single-chip programmable clock uses just one crystal to generate all the custom and low-EMI frequencies required for Femtocells
