OSCILLATORS
14-pin DIL compatible resistance welded enclosure,
hermetically sealed with glass to metal seal
14-pin DIL
250kHz to 80MHz
Tri-state HCMOS/TTL
Drive Capability: 50pF max or 10TTL
±5ppm or ±10ppm
±15ppm, ±25ppm, ±50ppm (over operating temperature
range)
Frequency Tolerance (as above)
Voltage Variation: < ±0.5ppm
Load Variation: < ±0.5ppm (< 60.0MHz)
Load Variation: < ±1.0ppm (> 60.0MHz)
Ageing for 5 years: < ±5ppm
0 to 70°C (IQXO-415)
–40 to 85°C (IQXO-415I)
–55 to 125°C
No connection or Logic ‘1’ to pin 1 enables oscillator output
Logic ‘0’ to pin 1 disables oscillator output; when disabled the
oscillator output goes to the high impedance state
Disable current 50µA typical
Acceleration: 490m/s
2
for 1 minute in the ‘Y1’ plane
Bump: 4000 bumps at 390m/s
2
in each of the three mutually
perpendicular planes
Hermetic Seal: not to exceed 1 x 10 mBar litres of Helium
