Frequency in MHz

Special Specifications (choose all that apply)

Model

H = < 70 MHz

D = 70 to 80 MHz

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

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

X: Supply Voltage of 1.8 volts ± 5% (must include)

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
