da6270

Manufacturer Part Number
da6270
Description
Ic For 6.50 ? 40.00 Mhz Vctcxo
Manufacturer
Micro Analog Systems Oy
Datasheet
DESCRIPTION
The MAS6270 is an integrated circuit well suited to
build
Temperature calibration is achieved in three
calibration temperatures only.
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
The trimming is
communication.
IC FOR 6.50 – 40.00 MHz VCTCXO
APPLICATIONS
To build a VCTCXO only a crystal is required in
addition to MAS6270. 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
