ACT have launched their smallest, ultra miniature HCMOS oscillator yet. The ACT92016S is only 2.0 x 1.6 x 0.75mm and is suitable for a wide range of applications where space is a constraint, such as compact portable and hand-held products. Ranking alongside the smallest oscillators in the world, its low power consumption and low voltage... View article
Definitions of frequently used key words when working with crystals. Aging Quartz crystal aging applies to the cumulative change in frequency over time, which results in a permanent change in the operating frequency of the crystal unit. The rate of change of frequency is fastest during the first 45 days of operation. Many interrelated factors... View article
In millimetric applications, an oscillator is a common module in many analogue circuits. The following article offers some suggestions of how to model the piezoelectric resonator that is its principal component. The RLC circuit representing the impedance of a crystal resonator is shown by a two-terminal equivalent in figure 1. The circuit above shows, the... View article
ACT have launched their comprehensive range of kHz clock oscillators. The ACT90H series covers frequencies between 14kHz and 100kHz, and all are available with a universal square wave output (10TTL/15pF HCMOS). Other features include: frequency stability of ±25ppm to ±100ppm over -10+70°C and also -40+85°C output enable option is standard duty cycle 45/55% max with... View article
