da6282

Manufacturer Part Number
da6282
Description
Ic For 6.50 ? 40.00 Mhz Vctcxo
Manufacturer
Micro Analog Systems Oy
Datasheet
DESCRIPTION
The MAS6282 is an integrated circuit well suited to
build
Temperature calibration is achieved in three
calibration temperatures only. The trimming is done
through a serial bus and the calibration information
is stored in an internal PROM.
FEATURES
This is preliminary information on a new
product under development. Micro Analog
Systems Oy reserves the right to make any
changes without notice.
Very small size
Minimum Vdd 2.6V
No voltage reference capacitor needed
Programmable VC-sensitivity
Divider option selectable by a PROM bit
Output waveform options: sine wave or CMOS
Output peak voltage (amplitude) option
selectable by a PROM bit in sine wave version
VCTCXO
for
mobile
communication.
IC FOR 6.50 – 40.00 MHz VCTCXO
APPLICATIONS
To build a VCTCXO only a crystal is required in
addition to MAS6282. The compensation method is
fully
generating any steps or other interference.
Output is either CMOS or a true sine wave resulting
in lower harmonics than with clipped sine wave
output.
Min. Supply Voltage 2.6 V
Max. Frequency 40 MHz
True Sine Wave Output
CMOS Output
Frequency Stability ±2.0 ppm
Suitable for Ultra Small
VCTCXO
Very Low Phase Noise
VCTCXO modules for mobile phones
VCTCXO modules for other applications
