Champion Inverted Mesa Crystal
Opens New Opportunities
November 1999: Champion Technologies is producing high frequency
inverted mesa fundamental-mode crystals, targeting applications
in precision high speed, low-jitter clocks as well as VCXOs,
VCTCXOs and custom low-jitter hybrid modules for datacomm applications.
The CIM-32 series was developed with Champion's proprietary processing
technology and is available immediately in frequencies ranging
from 51.84 MHz to 155.52 MHz. The CIM-32 Series offers low series
resistance, high pullability, and excellent unit-to-unit and
lot-to-lot repeatability. These devices are packaged in an industry
standard HC-45 package for through-hole or SMD mounting.
High frequency fundamental-mode crystals are increasing in demand
for applications such as precision high speed clocks, VCXOs and
VCTCXOs. However, conventional crystal processing utilizing flat
quartz blanks has limited the available frequency range to 55
MHz. Using higher quality, "swept" quartz, it has long
been possible to produce fundamental-mode inverted mesa crystals
with frequencies extending past 200 MHz. However, the higher
cost of materials, coupled with slower production throughput
have made these resonators undesirable for use in large volume
applications. As telecommunication equipment designers continue
to demand oscillators that operate at higher frequencies and
still retain the smallest possible size and tightest stability,
manufacturers have scrambled to fill this growing market. With
the introduction of Champions CIM-32 Series, designers can accomplish
these goals without breaking their budgets.
