Output Compatibility & Load
HCMOS/TTL
Drive Capability: 50pF max or 10TTL
Non tri-state (IQXO-35)
Tri-state (IQXO-36)
Frequency Tolerance @ 25°C (Optional)
±5ppm, ±10ppm, ±25ppm
Frequency Stabilities

Tri-state Operation (IQXO-36)
No connection or Logic ‘1’ to pin 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
= 20k
Disable current 50A typ
