oscillators
For clocking solutions in the 100 to 200 MHz band, and in smaller form factors than the PLL-based AX5 and AX7 devices, a new oscillator architecture is needed. These requirements for smaller sizes are typically associated with the latest-generation optical transceivers and modules. There are four established ways to design a clock oscillator in the range of 100 to 200 MHz:
Use a quartz oscillator with an inverted mesa quartz blank as the resonator element
Use a quartz oscillator with a third-overtone quartz blank as the resonator element
Use an oscillator loop based on a sub-50 MHz, third-overtone/fundamental-mode quartz blank, or a sub-50 MHz, temperature-compensated crystal oscillator mated with an integer or fractional-mode PLL IC
Use a sub-50 MHz microelectromechanical systems (MEMS) resonator-based oscillator loop mated with an integer or fractional-mode PLL IC
Use a quartz oscillator with an inverted mesa quartz blank as the resonator element
Use a quartz oscillator with a third-overtone quartz blank as the resonator element
Use an oscillator loop based on a sub-50 MHz, third-overtone/fundamental-mode quartz blank, or a sub-50 MHz, temperature-compensated crystal oscillator mated with an integer or fractional-mode PLL IC

Quartz Blanks
Quartz Blanks constitute the initial, but very important step of the production process for quartz frequency products (FCPs).

Generally speaking, there is an inversely proportional relationship between the resonant frequency of a quartz blank and the thickness of a quartz plate.
At the resonant frequency, an odd number of half the acoustic wavelength fits in the thickness plane of the quartz blank. Therefore, the thickness of a blank is the main frequency-determining dimension of quartz produced in the AT-section. AT-section quartz crystals are commonly manufactured in the following frequency ranges:
1 MHz ~ 60 MHz, operation in fundamental mode
30 MHz ~ 250 MHz, operation in overtone mode (3rd; 5th; 7th; 9th overtone)

A tam! "nie pomagają"... Wink Z polskiej Wikipedii (w haśle Rezonator kwarcowy): "Każdy rezonator obok częstotliwości podstawowej (tzw. mod podstawowy), może też drgać z częstotliwościami ponadpodstawowymi (tzw. owertony - zwykle nieparzyste wielokrotności modu podstawowego) oraz pasożytniczymi."
Chodzi o to, że rezonatory o wyższysch częstotliwościach (powyżej ok. 20 MHz) wykonywane są zwykle jako tzw. overtonowe, tzn. wykorzystuje się drgania płytki kryształu kwarcu (odpowiednio ciętej) na częstotliwościach harmonicznych (np. 3, 5, itd). Np. w generatorze odniesienia dla DDS'a (Buttler) w PIC-a-STAR wykorzystuje się rezonator w ten właśnie sposób, uzyskując generacje na 5 albo 7 harmonicznej.
