A DROP-IN REPLACEMENT SOLUTION FOR YOUR EMI / EMC COMPLIANCE PROBLEM.
WHY RE-LAYOUT THE BOARD WHEN YOU CAN HAVE DROP-IN SOLUTION?
The principle sources of the EMI problem
come from the system clocks. Therefore, rather
than patch the problem with ferrite beads, EMI
filters, ground plane and metal shielding, the most
efficient and economic way to reduce the peak
radiation energy is to use the low EMI clock
oscillator.
Compared with the conventional clock
oscillators, Mercury HM57 series spread spectrum
(dithered) clock oscillators can reduce EMI as
much as 12 dB.
3HM57 reduces your EMI
and shorten your time to market.
Applications
Printers; Multiple function printers (MPCs)
Digital copiers; PDAs
Networking; LAN / WAN; Routers
Storage systems
(CD-ROM,
VCD, DVD and HDD)
Scanner; Modems; projectors
Hand-held ID readers
Modulation Types
Embedded systems; Electrical musical instrument
Automotive; GPS car navigation systems
LCD PC monitors / LCD TVs
ADSL; PCMCIA
Still Digital cameras (SDCs)
Spread Spectrum Clock (SSC):
Unlike the conventional clock, the
mode energy of a spread spectrum
clock is spread over a wider
bandwidth, resulting from the
frequency modulation
technique. The
modulation carrier frequency is in the
KHz range which makes the
modulation process transparent to the
oscillator frequency. The controlled
modulation process can be on all of
one side of the nominal frequency
(down
spread)
or 50% up and 50%
down (center
spread).
The down
spread is preferred if
over-clocking
is
a problem to the system.
