ANENG-ODP-000 Oscillator Design Pitfall & Reliability Consideration for IC Designers – Lay out
(Quartz Crystals can be found easily in any electronic products nowadays. They are apparently easy to use but in fact many electronic engineers found difficulties when high precision and high reliability are required. IC Designers are welcome to contact us for organizing a seminar in person or by video – we will present the mysteries behind and precautions for properly using a quartz crystal)
