Crystals and oscillators get smaller

摘要

As devices continue to shrink in size, so does the need to miniaturize electronic components. In recent months, frequency control manufacturers have focused on the miniaturization of both quartz crystals and oscillators. Improving jitter performance and stability along with helping optimize power consumption are also on the to-do list as the industry moves to higher-speed communications.One example is Micro Crystal AG's 32.768-kHz quartz crystal that is housed in a footprint that measures 1.6×1.0 mm with a maximum thickness of 0.35 mm. The new tiny geometry enhances the circuitry in applications in which bending radii are critical and complements the new bendable thin-film batteries from Renata, said the company. Applications include smart cards, e-textile, wearables (including activity bands), embedded modules, and health care. Both the low-frequency CM9V-T1A crystals (1.6 × 1.0 × 0.3 mm) and CM8V-T1A (1.6 × 1.0 × 0.3 mm) are available in volume production.
