Output Compatibility
■
Tri-state HCMOS/TTL (5.0V) (IQXO-70)
■
Tri-state HCMOS (3.3V) (IQXO-71)
Package Outline
■
SMD (surface mount device) ceramic package.
Available over –10 to 70°C (IQXO-70, -71) or
–40 to 85°C (IQXO-70I, -71I)
Standard Frequency Stabilities
■
±25ppm (not available over –40 to 85°C), ±50ppm,
±100ppm (inclusive of supply voltage & output load
variations over the operating temperature range)
Operating Temperature Range
■
–10 to 70°C (IQXO-70, -71)
■
–40 to 85°C (IQXO-70I, -71I)
Storage Temperature Range

Tri-state Operation
■
Logic ‘1’ to pad 1 enables oscillator output, 2.2V min
■
Logic ‘0’ to pad 1 disables oscillator output; when
disabled the oscillator output goes to the high
impedance state, 0.8V max
■
No connection to pad 1 enables oscillator output
