20 = ± 20 PPM

Y: Std Specs (5.0V ± 10%, 0 to +70 C, 40/60% Symmetry)

E: Extended Operating Temperature Range (- 40 to +85 C)

S: 45/55% Symmetry at 50% of Vcc

V: Supply Voltage of 3.3 volts ± 10%

W: Supply Voltage of 2.5 volts ± 5%

X: Supply Voltage of 1.8 volts ± 5% (Consult factory)

Consult factory for available frequencies and specs. Not all options available for all frequencies. A special part number may be assigned.

Frequency Stability is inclusive of frequency shifts due to calibration, temperature, supply voltage, shock, vibration and load
