SMD Crystal Oscillators
DSO221SR/DSO321SR/DSO321LR/DSO531SR/DSO751SR
Features
Low current consumption: 6mA MAX (125MHz, 3.3V)
Low voltage operation: 1.8V/2.5V/2.8V/3.3V
● Offers Narrow deviation: ±20×10-6/±30×10-6/
±50×10-6/±100×10-6
● Available up to 150MHz by using AT cut fundamental
resonator. Low jitter provides for high performance.
● Low profile: 0.82mm (DSO221SR), 0.855mm
(DSO321LR), 1.1mm (DSO321SR/DSO531SR),
1.5mm (DSO751SR)
