8-pin DIL
500kHz to 160MHz
HCMOS/TTL
Drive Capability: 50pF max or 10TTL (<70.0MHz)
30pF max (70.0 to 160.0MHz)
Non tri-state (IQXO-22, -22I)
Tri-state (IQXO-23, -23I)
±25ppm, ±50ppm, ±100ppm (over operating temperature
range)
0 to 70°C (IQXO-22, -23)
–40 to 85°C (IQXO-22I, -23I)
–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
Maximum ‘pull-down’ resistance required to disable
output = 20kΩ
Disable current 50µA typical
Terminal Strength: 0.91kg max force perpendicular to top and
bottom
Hermetic Seal: not to exceed 1x10 mBar litres of Helium
