MAS9281
IC FOR 10.00 – 60.00 MHz XO
• Low Cost
• Divider Option up to fo/512
• Wide Supply Voltage Range
• CMOS Output
• Very High Level of Integration
• Very Low Phase Noise
• Output Three-State Function
DESCRIPTION
MAS9281 is an integrated circuit well suited to
make fundamental crystal oscillator (XO): only one
additional component, a crystal is needed.
FEATURES
• Very small size
• Minimum current draw
• Stand-by functions: Output high impedance, but
oscillator running. Output high impedance and
oscillator stop
• Wide operating temperature range
• Phase noise <-130 dBc/Hz at 1 kHz offset
• CMOS output
BLOCK DIAGRAM
MAS9281 includes oscillator and output buffer
circuits.
APPLICATIONS
• XO for data terminals
• XO for telecommunication applications
• XO for computer application
