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
