NOTES
OUTPUT VOLTAGE
Output voltage can be to custom specification or standard at
2.25V min. for +3.3V supply or 3.95V min. for 5.0V supply.
To achieve necessary logic levels provide terminating scheme
information when ordering or use terminating resistors
recommended by Euroquartz.

Note: For non-standard frequency stability for commercial temperature
range use the Code’C’ followed by the stability, example ‘C20’ for
±20ppm over 0° to +70°C. For industrial temperature range use ‘I’
and the stability, example ‘I20’ for ±20ppm over -40° to +85°C.
