VF594

The VF594 is a kind of ECM surface mount VCXO and its environmental & mechanical are mechanical shock: Mil STD 202 Method 213 cond E; thermal shock: Mil STD 883 Method 1011 cond A; vibration: MIL-STD-883 Method 2007 cond A; soldering condition: 260°C for 10s max: 230°C for 90s max; hermetic seal leak rate less than 5x10 -8 Atm.cc/s of helium.

The features of VF594 can be summarized as (1)wide frequency range; (2)very low phase jitter; (3)wide pullability; (4)standard footprint; (5)wide operating temperature; (6)EMI shielded.
