V or blank = (V = Volt.Trim) (Blank = Mech. Trim)
Letter = Operating Temperature (see table 1)
Letter = Frequency Stability (see table 1)
3 or blank = Input Volt (3 = 3.3 volts) (Blank= 5V)
Frequency in MHz: 3 or 6 decimal places
Example:
CXOSD4-BC3-25.000 = mech. trim, -10/60, ±2.5ppm, 3.3V, 25.000 MHz
